It includes an I2C serial interface for accessing the digital features of the MSL3162 LED driver. It has onboard switches that set the I2C slave address to one of four available addresses, a switch to set the full-scale LED current to 50, 60, 70, or 80mA in single-string mode, and 100, 120, 140, or 160mA in dual-string mode, and a switch to set the maximum LED voltage to 39, 36, 32, or 28V. The board is powered from a single input voltage between 10V and 16V. Input Power The MSLB9082 board is powered from a single input voltage ranging from 10 to 16V. Setting the Full-scale LED Current The MSL3162 regulates the LED string current. The LED string current is set by a current sense resistor. Four different values are programmed to the MSLB9082 LED driver module, and switch S2 selects one of those resistors to set the full-scale, per-string LED current to 50, 60, 70, or 80mA. Table 4 shows the switch settings and the full-scale, per-string LED current for each setting.

The ISTRn register is a 6-bit word that sets the LED current for each LED string to one of 64 linear levels. The per-string LED current is: ISTRn = ISTR_FULL ISTRn+1 64 , where ISRTn is the current of LED string n, ISTR_FULL is the full-scale LED current set by S2, and ISRTn is the value of the current setting register for string n between 0 and 64 (0x3F). Atmel LED Driver-MSLB9082 9 I2C Serial Interface The MSLB9082 driver module uses an I2C/SMBus serial interface for digital LED control and fault detection. Four slave ID addresses are available, and are selected by the I2C address selection switch. The addresses are shown in table 5.

The PWM dimming frequency is programmable, as are the PWM duty cycle and phasing between LED strings. For DMAX>1, the maximum duty cycle is 100%. Setting the LED PWM Dimming Duty Cycle The MSL3162 allows each LED string to operate at different duty cycles and phases. The per-string PWM dimming duty cycle for any LED string is set by the PWMn register, where n is the LED string number. The MSL3162 also offers PWM dimming of all strings simultaneously through the global intensity (GINT) register. Each string PWM on time is set by the eight most-significant bits of the product of the PWMn and GINT registers, multiplied by the GSC period: Setting the PWM Dimming Frequency The PWM frequency (PHI frequency) is internally set by the IPHIGEN register. This 16-bit number sets the divider ratio from an internal 2.5MHz clock. Therefore, the PWM frequency is: f PWM = 2.5MHz IPHIGEN 1 t ON_PWMn =  f  GSC   PWMn * GINT  *   64   For high dimming accuracy, keep the PWM dimming frequency below 10kHz. To set the PWM frequency, program the IPHIGEN register between 38Hz and 10kHz per the equation:  IGSCGEN − 1   PWMn * GINT  t ON_PWMn =   * 64   20 MHz   IPHIGEN = 2.5MHz , f PWM where PWMn ranges from 0 to 256 (0xFF) and GINT ranges from 0 to 64 (0x3F). where IPHIGEN ranges between 250 (0x00FA) and 65535 (0xFFFF) For full PWM dimming resolution, make sure that the ratio between the IGSCGEN register and IPHIGEN register is 32. See Setting the PWM Dimming Resolution for more details. Setting the LED PWM Dimming Phasing Each LED string’s PWM dimming occurs with independent phasing. This is useful to force phase shifted PWM dimming, which reduces the transient load on the DC-DC converter, improving performance. The phase of each LED string is set by PHDLYn, where n is the LED string number. The MSL3162 counts GSC pulses to determine the on-time delay from the beginning of each PHI frame. For example, if PHDLY0 is set to 0x00, the LED string 0 on time starts at the beginning of a PHI frame. If PHDLY0 is set to 0x40, the LED string 0 on time begins at 64 (0x40) GSC pulses after the beginning of a PHI frame. Setting the PWM Dimming Resolution The MSL3162 uses the IPHIGEN register to set the PWM dimming frequency, and it uses the IGSCGEN register to set the PWM dimming resolution (GSC frequency). The MSL3162 internally counts using the frequency set by the IGSCGEN register to set the PWM duty and phasing. Full PWM dimming is achieved if the ratio of IGSCGEN to IPHIGEN is less than 32. If the ratio is greater than 32, then the maximum achievable duty cycle is: 1 t PHDLYn =  f  GSC   * PHDLYn    IGSCGEN − 1  DMAX = 32 ×    IPHIGEN   IGSCGEN − 1  t PHDLYn =   * PHDLYn  20 MHz  Atmel LED Driver-MSLB9082 13 Setting the LED Voltage Range The MSL9082 LED driver board uses four different voltage ranges to power the LEDs, which are set through the S3 switch. The ranges are shown in Table 7. The MSL3162 automatically adjusts the LED voltage over a 7.4V range to minimize power loss while maintaining enough current sink headroom to keep the LED string current accurate. Choose an LED voltage range that suits the LEDs used so that the MSL3162 can adjust the voltage to optimize for the LED voltage. For more information, consult the MSL3162 data sheet. Table 6: LED Voltage Settings VOLTAGE SWITCH S3 POSITION LED VOLTAGE RANGE VOLTAGE SWITCH S3 POSITION LED VOLTAGE RANGE 28.8V to 21.3V Position 1 Position 3 37.1V to 29.6V 39.7V to 32.3V Position 2 Position 4 33.0V to 25.6V 14 Atmel LED Driver-MSLB9082 Atmel LED Driver-MSLB9082 LED Backlight Driver Module Compact, 8-channel, 20W LED Driver Board with I2C Interface On/Off (EN) Control Input The on/off control input, pin 9 of input connector J2, turns on/off the LED driver. Drive it high (between 2.3 and 5V) to turn on the LED driver, and drive it low (0 to 0.8V) to turn it off. The on/off control input is internally pulled up by a 100kΩ resistor. For automatic start-up, leave EN unconnected. Fault Indicator Output The MSL3162 includes fault detection circuitry that detects and open-circuited LED string, and an LED string with one or more short-circuited LEDs. If any fault is detected, the output is driven low. Use this output as an alert signal to a system controller. Once the controller gets the alert signal, it determines which LED is faulty by reading the STATUS, OCSTATUS, and SCSTATUS registers through the I2C serial interface. External PWM Control Input The MSL3162 operates in one of three modes: internal PWM mode, external PWM mode, or gated PWM mode. Internal PWM mode dims the LEDs with a frequency and phase set by the MSL3162, and the state of the PWM input is ignored and has no effect on LED brightness. In this case, each string can have a different PWM set by the MSL3162’s PWMn register setting. To control the brightness of all LEDs simultaneously, set the GINT register between 0 and 3F. External PWM and gated PWM modes use the duty cycle of the signal applied to the PWM input; connector J2, pin 10. The PWM input is pulled high through a 100kΩ resistor. If not used, leave PWM unconnected or drive it high. The MSL3162 digitizes the PWM input signal and determines the duty cycle of that signal. This value replaces the GINT register value to control the global brightness (of all LEDs simultaneously). In this case, individual string brightness is controlled through the PWMn register. Gated PWM mode turns on all LEDs when PWM is driven high, and turns them off when PWM is driven low. By programming the PWMn registers and GINT for 100% duty cycle, the LEDs are directly PWM dimmed by the signal applied to the PWM input. Connecting the LEDs to the Atmel LED DriverMSL9082 LED Driver The MSLB9082 driver board drives LED arrays with up to eight parallel strings of up to 12 series LEDs each through the output connector, J3. Eight connections for LED cathode connections allow the use of separate LED strings or common-anode-connected LED strings. Driving LEDs with Greater than 80mA LED Current The MSL3162 is capable of driving up to 80mA per LED string. The MSLB9082 board has two string drivers connected to each driver connection (STRASTRH), with one disabled. This allows driving up to 180mA per LED string by enabling the two drivers and setting the same PWM duty ratios and phasing for both MSL3162 driver inputs (dual-string mode). See the MSL3162 datasheet for more details on programming the MSL3162. Table 8 shows the switch settings and the full-scale, per-string LED current for each setting when operating in parallel mode.
