BD6086GU

System LED Drivers for Mobile Phones 13LEDs ALC* Flash and Illumination (*ALC : Auto Luminous Control) BD6086GU No.11041EAT16 ●Description BD6086GU is a composite LED driver best-suited for mobile phone display. With an analog illumination intensity sensor connected, this LED driver mounts an auto luminous control (ALC) function capable of automatically adjusting the backlight current depending on an ambient illumination intensity to reduce the set power consumption. With a key backlight driver mounted, this driver enables the ON/OFF setting to be made depending on the ambient illumination intensity. In addition, this driver realizes an eye-catching display through the use of two RGB LED drivers supporting a slope control function. With two channels of variable output type regulators mounted, this driver can be used for LCD and camera. This driver eliminates the need for additional wirings on a flexible substrate through the GPIO mounted. 2 The DC/DC module adopts a charge pump system and rarely uses a coil. Furthermore, it employs a VCSP85H4 (4.5mm 0.5mm pitch) chip size package for compaction and thinness. ●Futures 1) LED Driver (7ch) for LCD Backlight ・Incorporates 4 channels for main settings and 3 channels optionally selectable for either independent control or main setting depending on register settings. ・Provides a driver assigned for main settings with various functions such as an automatic current value adjustment function by an illumination intensity sensor, a slope control function against current value variation, an LED current value adjustment function for reflecting a setting value in a register through external pin synchronization and an LED current value adjustment function through external pin PWM input. 2) RGB LED driver (dual driver) ・Incorporates a slope control function (capable of controlling dual drivers independently) ・Capable of selecting (setting) a battery or DC/DC output module as a destination (register setting) ・Capable of using one driver for GOP output mode (register setting) 3) Illumination intensity sensor interface ・Incorporates various functions such as a sensor bias adjustment function, an ADC with an average filter, a gain/offset adjustment function and an LOG conversion function so that options can be increased for illumination intensity sensors (Photo Diode, Photo Transistor, Photo IC (Linear/LOG)). ・ Incorporates an auto gain switching function for suppressing an illumination intensity sensor current at high illumination intensity and improving sensitivity at low illumination intensity ・Capable of customizing an LED current value according to a table setting. 4) Built-in regulator (2 channels) ・REG1 2.8V Iomax=150mA Low power consumption mode available ・REG2 1.5V/1.8V Iomax=150mA Low power consumption mode available ・REG1, REG2 Both can be controlled independently via external pins. 5) Charge pump system DC/DC ・Supports an output voltage fixed mode function (3.9V/4.2V/4.5V/4.8V) ・Mounts a soft start function, an overvoltage protection function (auto recovery type) and an overcurrent protection (auto recovery) 6) Key backlight controller ・Capable of ON/OFF control depending on an ambient illumination intensity ・Capable of adjusting key backlight brightness via MAX DUTY setting ・Capable of making an fade-in/fade-out setting via PWM 7) Built-in general-purpose port (4 channels) ・GPIO4ch ・Permits the selection of a complementary or open drain for output. 8) Thermal shutdown 2 9) I C BUS Fast mode support (max. 400 kHz) * Radiation-proof is not designed. * This Description is subject to change without a prior notice. * This Description is not a delivery specification. www.rohm.com © 2011 ROHM Co., Ltd.

This function makes it possible to assign the drivers easily depending on set designs such as main 4 LEDs/sub 2 LEDs/indicator 1ch and main 6 LEDs/sub 1 LED. ・ Implements control as shown below when main group setting is designated via the W*MD bit. Current setting: Operates in conjunction with IMLED(6:0) (IW*(6:0) is discarded.) ON/OFF control: Operates in conjunction with MLEDEN. (W*EN is discarded.) ・ Enables the main group to control PWM via the external terminal so that brightness control can be accomplished from the outside. PWM control: Inputs PWM via the external terminal “WPWMIN.” External synchronization: Corrects a current value set by IOFS (5:0) in synchronization with the external terminal “OSYNC.” ・ Determines the LED current via a built-in resistance. Permits the main group to perform slope processing so that the leading/trailing edge time can be set individually. The settings made in the registers THL (3:0) and TLH (3:0) are effective regardless of their light control mode (ON/OFF). To enable instant activation, the minimum value must be set for time. ●RGB LED Driver Operation Description ・ Two drivers “RGB1 (R1LED, G1LED, B1LED)” and “RGB2 (R2LED, G2LED, B2LED)” are mounted. ・ A slope function is incorporated to control drivers independently. ・ Refer to  RGB Waveform Setting for more information about output waveform setting. ・ RGB2 can be used for GPO (Open drain output) It can be set up in every terminal with the register R2GPO, G2GPO and B2GPO. ・ The LED current can be set via a resistance value (RISET) to be connected to the RGBISET terminal. The maximum current value can be derived from the following expression: ILEDmax [A] = 3.048 / RISET [kΩ] (Typ) However, this setting must be made so that the maximum current value can be less than or equal to 30.48mA. In addition, the RGBISET terminal has an overcurrent protection circuit to prevent the excessive LED current from flowing for low impedance to the ground. ・ Connection of each LED of RGB can be set up in VBAT or VOUT by the register RGB1PW (1:0) and RGB2PW (1:0). When Vf is low, it is connected to VBAT, and it is possible that efficiency is raised. When a VBAT connection is chosen, a return route to the DC/DC circuit is interrupted, and it works as a simple constant current driver. In this case, set it up to be less low than the saturation voltage (0.2V) of the fixed electric current circuit. LED electric current When DC/DC isn't used.

Capable of selecting a complementary or open drain output method so long as GPO is selected. Uses a VGPIO applied voltage as a logic level (during CMOS output setting and input setting). When open drain output is selected, a pull-up resistance may be connected to a desirable location (VPUP) but the condition of VGPIO≧VPUP must be satisfied. ・ Capable of outputting an interrupt signal via the INTB terminal (NMOS open drain) depending on an input logic change 2 in each terminal and reading an input logic and an interrupt factor via I C so long as GPI is selected. Reflecting interrupts can be selected individually. When input mask is set: An input logic is sampled at the leading edge of a clock (having a frequency obtained by dividing 32KIN by 256). When a sampling value differs from the contents of the existing output register consecutively three times, it is reflected on the output register (input logic and interrupt factor). No input logic change is reflected on the INTB output. When input mask is reset: An input logic is sampled at the leading edge of a clock (having a frequency obtained by dividing 32KIN by 256). When a sampling value differs from the contents of the existing output register consecutively three times, it is reflected on the output register (input logic and interrupt factor). In addition, an interrupt pulse (one cycle of 32KIN with negative logic) is output simultaneously via INTB. The interrupt factor can be cleared by setting GPCLR (Address=23h, Bit=7) to H. ・ Provide an idle GPIO terminal with a resistance of about 100kΩ for pull-down. (When GPIO1 to GPIO4 and KBLT are not used at all, short-circuiting of VGPIO and GND eliminates the need for using this pull-down resistance.) ・ Each terminal of the GPIO block is initially set as follows: GPIOs1-4: I/O mode When using the output mode: The breakthrough current flows on an input buffer circuit until the output mode is set. When there is a problem, be sure to connect a pull-down resistance. Once the output mode is set, the input buffer circuit must be set to OFF so that the breakthrough current cannot flow. When using the input mode: The breakthrough current flows on an input buffer circuit unless an input voltage is fixed. When there is a problem, be sure to connect a pull-down resistance to fix the input voltage. KBLT: L (A pull-down resistance is incorporated to prevent unstable output at voltage supply.) INTB: Employs an external pull-down to set “H” for open drain output. ・ ・ ・ www.rohm.com © 2011 ROHM Co., Ltd.

VIO and VGIO may be short-circuited. Even when only GPIO is used, voltage should apply to VIO too. To avoid erroneous output to the INTB terminal at activation time, don’t reset the input mask of GPIO* prior to an elapse of 30ms after 32KN input. Because internal IO is activated at clock input, current dissipation arises even in the standby state. When there is a problem, stop 32KIN input.

This value is identical to that at Typ (1MHx). ・ Enables the selection of complementary or open drain for output and allows diversion to GPO. ・ Uses a VGPIO applied voltage as a logic level (during CMOS output setting and input setting). When open drain output is selected, a pull-up resistance may be a desirable location (VPUP) but the condition of VGPIO≧VPUP must be satisfied. ・ Mandatory to supply voltage to VGPIO for key backlight controller operations. For a key backlight controller operating in conjunction with an auto luminous control (ALC) module The register “KBFIX” must be set to 0 to enter the auto luminous control mode. The ON/OFF condition to illumination intensity is set in the registers CTH (3:0) and CHYS (1:0). The ON/OFF patterns of the key backlight are set in the registers MDTY (3:0) and KBSLP (1:0). (For details of auto luminous control module setting, refer to ●Description of Auto Luminous Control Module Operations.) For a key backlight controller capable of ON/OFF control according to register settings The register “KBFIX” must be set to 1 to enter the register setting mode. The slope time is set in the register “KBSLP (1:0).” When the key backlight is turned ON, data equivalent to illumination intensity must be set in MDTY (3.0). When it is turned OFF, “0h" must be set instead. For a key backlight controller to be used as GPO The register “KBFIX” must be set to 1 to enter the register setting mode. The register "KBSLP (1:0)” is set to 00 (without slope). When “H” level output takes place as a GPO, the register “MDTY (3:0)”must be set to Fh. In contrast, when "L" level output takes place, the MDTY (3.0) must be set to 0h instead. www.rohm.com © 2011 ROHM Co., Ltd.

To activate a RGB waveform, a continuous operation via RGB*EN or a single-shot operation via RGB*OS can be selected. In addition, when control via the external terminal RGB*CNT is enabled via RGB*MEL, the corresponding LED can be lit in synchronization with the external signal. 1. Waveform cycle ・ingle cycle time is set for a waveform pattern. ・This setting can be made independently for RGB1 and RGB2. 2. Waveform pattern ・A pattern in a waveform cycle is set. ・Sixteen types of waveform patterns can be set in units of waveform patterns. ・For concrete waveform patterns, refer to the timing diagram shown on the next page. 3. Current settings 1 and 2 (I1, I2) ・Two currents in a waveform pattern are set. ・When the maximum current value is 25.4mA, it is possible to set the current ranging from 0 to 25.4mA with an increment of 0.2mA (128 steps). ・The polarity of a waveform is determined by the greater-than/ less-than relationship in the current setting. ・This setting can be made in units of terminals. 4. Rising/falling slope time ・A current change time during switching between current settings 1 and 2 is set. A time per step (0.2mA) is calculated based on a difference between the currents selected in current settings 1, 2 and a setting slope time. For this reason, a time per step (0.2mA) is short when a difference between setting currents I1 and I2 is large. In contrast, it is long when a difference between setting currents I1 and I2 is small. ・Regardless of current settings 1 and 2, a rising slope time applies at current increase and a falling slope time applies at current decrease. For concrete waveform images, refer to the timing diagram shown on the next page. 5. External terminal synchronization control When control via the external terminal RGB*CNT is enabled via RGB*MEL, lighting is enabled if the input external signal goes “H.” In contrast, it is disabled if the external input signal goes “L.” In this way, synchronization with the external signal is enabled so that LED can be blinked in conjunction with a ringing tone (a melody signaling a ringtone).

(1) Software reset ・Setting the register (SFTRST) to “1” causes all the registers to be initialized. ・The registers subject to software reset automatically return to zero (Auto Return 0). (2) Hardware reset ・Changing the RESETB terminal setting from “H” to “L” causes a state subject to hardware reset. ・Attempting hardware reset causes the states of all registers and output terminals to be initialized to their initial values, so that address reception is entirely stopped. ・Attempting reset in the hardware reset state causes the RESETB terminal state to change from “L” to “H” and vice versa. ・The RESETB terminal is provided with a filter circuit and a duration of 5µs or less with the terminal set to “L” is not recognized as hardware reset. (3) Reset sequence ・When hardware reset is attempted during software reset, software reset is already cleared when hardware reset is cleared (because the software reset initial value is 0). 2.Thermal shutdown A thermal shutdown function is effective in the following block.

All rights reserved. 77/80 2011.04 - Rev.A BD6086GU Technical Note ●Notes for use (1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc. (2) Power supply and ground line Design PCB pattern to provide low impedance for the wiring between the power supply and the ground lines. Pay attention to the interference by common impedance of layout pattern when there are plural power supplies and ground lines. Especially, when there are ground pattern for small signal and ground pattern for large current included the external circuits, please separate each ground pattern. Furthermore, for all power supply pins to ICs, mount a capacitor between the power supply and the ground pin. At the same time, in order to use a capacitor, thoroughly check to be sure the characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant. (3) Ground voltage Make setting of the potential of the ground pin so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no pins are at a potential lower than the ground voltage including an actual electric transient. (4) Short circuit between pins and erroneous mounting In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between pins or between the pin and the power supply or the ground pin, the ICs can break down. (5) Operation in strong electromagnetic field Be noted that using ICs in the strong electromagnetic field can malfunction them. (6) Input pins In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input pin. Therefore, pay thorough attention not to handle the input pins, such as to apply to the input pins a voltage lower than the ground respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input pins when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input pins a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics. (7) External capacitor In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc. (8) Thermal shutdown circuit (TSD) This LSI builds in a thermal shutdown (TSD) circuit. When junction temperatures become detection temperature or higher, the thermal shutdown circuit operates and turns a switch OFF. The thermal shutdown circuit, which is aimed at isolating the LSI from thermal runaway as much as possible, is not aimed at the protection or guarantee of the LSI. Therefore, do not continuously use the LSI with this circuit operating or use the LSI assuming its operation. (9) Thermal design Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (Pd) in actual states of use. (10) LDO Use each output of LDO by the independence. Don’t use under the condition that each output is short-circuited because it has the possibility that an operation becomes unstable. (11) About the pin for the test, the un-use pin Prevent a problem from being in the pin for the test and the un-use pin under the state of actual use. Please refer to a function manual and an application notebook. And, as for the pin that doesn't specially have an explanation, ask our company person in charge. (12) Rush Current Rush current may flow in instant in the internal logic unfixed state by the power supply injection order and delay. Therefore, be careful of power supply coupling capacity, a power supply and the width of grand pattern wiring, and leading about. (13) About the function description or application note or more. The function manual and the application notebook are the design materials to design a set. So, the contents of the materials aren't always guaranteed. Please design application by having fully examination and evaluation include the external elements. www.rohm.com © 2011 ROHM Co., Ltd.
