SCL cannot change signal of SDA during H at the time of bit transfer. If SDA changes while SCL is H, START conditions or STOP conditions will occur and it will be interpreted as a control signal. SDA SCL SDA a state of stability： SDA It can change Data are effective ・START and STOP condition When SDA and SCL are H, data is not transferred on the I2C- bus. This condition indicates, if SDA changes from H to L while SCL has been H, it will become START (S) conditions, and an access start, if SDA changes from L to H while SCL has been H, it will become STOP (P) conditions and an access end. SDA SCL S START condition P STOP condition ・Acknowledge It transfers data 8 bits each after the occurrence of START condition. A transmitter opens SDA after transfer 8bits data, and a receiver returns the acknowledge signal by setting SDA to L. DATA OUTPUT BY TRANSMITTER not acknowledge DATA OUTPUT BY RECEIVER acknowledge SCL 1 2 8 clock pulse for acknowledgement 9 S START condition www.rohm.com © 2011 ROHM Co., Ltd.

The 3rd byte writes data in the internal register written in by the 2nd byte, and after 4th byte or, the increment of register address is carried out automatically. However, when a register address turns into the last address, it is set to 00h by the next transmission. After the transmission end, the increment of the address is carried out. *1 *1 S X X X X X X X 0 A A 7 A 6 A 5 A 4 A 3 A 2 A 1 A 0 A D7 D6 D5 D4 D3 D2 D1 D0 A slave address R /W=0(write) from master to slave from slave to master register address D ATA D7 D 6 D 5 D 4 D 3 D 2 D1 D0 A P DATA register address increment A =acknowledge(SD A LOW) A =not acknowledge(SDA HIGH) S=START condition P=STOP condition *1: Write Timing register address increment ・Reading protocol It reads from the next byte after writing a slave address and R/W bit. The register to read considers as the following address accessed at the end, and the data of the address that carried out the increment is read after it. If an address turns into the last address, the next byte will read out 00h. After the transmission end, the increment of the address is carried out.

The data of the address that carried out the increment is read after it. If an address turns into the last address, the next byte will read out 00h. After the transmission end, the increment of the address is carried out.

It stops with read when ending by A(acknowledge), and SDA stops in the state of Low when the reading data of that time is 0. However, this state returns usually when SCL is moved, data is read, and A(not acknowledge) is done. www.rohm.com © 2011 ROHM Co., Ltd.

The explanation of Reset There are two kinds of reset, software reset and hardware reset. ●Software reset ・All the registers are initialized by SFTRST="1". ・SFTRST is an automatically returned to "0". (Auto Return 0). ●Hardware reset ・It shifts to hardware reset by changing RESETB pin “H” → “L”. ・The condition of all the registers under hardware reset pin is returned to the initial value, and it stops accepting all address. ・It’s possible to release from a state of hardware reset by changing RESETB pin “L” → “H”. ・RESETB pin has delay circuit. It doesn’t recognize as hardware reset in “L” period under 5μs. ・Even if RESETB=L, at FLASHCNT=H, Flash mode becomes ON by minimum setting. ●Reset Sequence ・When hardware reset was done during software reset, software reset is canceled whenhardware reset is canceled. (Because the initial value of software reset is “0”) 2. The explanation of Thermal shutdown The blocks which thermal shutdown function is effective in the following. Charge pump LED Driver LDO1, LDO2, SBIAS o A thermal shutdown function works in about 190 C. o Detection temperature has a hysteresis, and detection release temperature is about 170 C.(Design reference value) 3. The explanation of Charge Pump for LED driver Charge Pump block is designed for the power supply for LED driver. It has the x1.0/x1.33/x1.5/x2.0 mode. It changes to the most suitable mode automatically by Vf of LED and the battery voltage. It has the mode of x1.33 and it can be higher efficiency than traditional. ●Start Charge Pump circuit operates when any LED turns ON. ●Soft start When the start of the Charge Pump circuit is done, it has the soft start function to prevent a rush current.

At this time, the maximum output voltage of the charge pump is restricted to 5.1V (typ). < Mode Down > The rise in the battery voltage, the off control of LED lighting, “Main Group” LED current value and the data writing to the address 04h,05h,06h (LED Current Setting) is monitored, and the movement mode is changed to ×2→×1.5→×1.33→×1 automatically. This mode down movement lasts until a mode up movement happens. At Flash mode and Torch mode, the mode down doesn't happen. The thresholds of rise in a battery voltage are 2.9V, 3.3V, 3.7V and 4.1V (typ). And, as for the off control of LED lighting, it is shown that MLEDEN, SLEDEN, TORCHEN, FLASHEN and FLASHCNT transited in “1” →“0”. ●Over Voltage protection / Over Current protection Charge Pump circuit output (VOUT) is equipped with the over-voltage protection and the over current protection function. A VOUT over-voltage detection voltage is about 5.5V(typ). (VOUT at the time of rise in a voltage) A detection voltage has a hysteresis, and a detection release voltage is about 5.1V(typ). And, when VOUT output short to ground, input current of the battery terminal is limited by an over current protection function. www.rohm.com © 2011 ROHM Co., Ltd.

All rights reserved. 38/41 2011.04 - Rev.A BD6095GUL,BD6095GU 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) About the rush current For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal powering sequence and delays. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of wiring. (13) About the function description or application note or more. The function description 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.
