Atmel LED Driver-MSL3085
8-string White and RGB LED Driver with Adaptive Power
Control, EEPROM, and I 2 C/SMBus Serial Interface
Direct PWM Control of the LED Strings
An external PWM signal applied to the PWM input allows direct PWM control over the strings when PWMEN and
PWMDIRECT (bits D0 and D1 in PWM control register 0x2D) are set to 1. This configuration bypasses PHI and GSC, but
allows LED string phase delay via the phase delay enable bit, PHADLYEN (bit D0 of register 0x2E). With phase delay
enabled, a progressive delay based on the period of the PWM frame is calculated and applied successively to each string
drive signal. The delay is typically 1/8 th the PWM frame, but outputs 9 and 12 have sequential delays of 3/16 th and 1/16 th
of the PWM frame, respectively.
The PWM input can also be configured as a gate for the output of the PWM engine using PWM global enable (bit D2 of
the PWM control register 0x2D).
Register Map and the EEPROM
Register Map Summary
Control the MSL3085 using the registers in the range 0x00 - 0xBD (Table 2). Two additional registers, 0xC0 and 0xC1,
allow access to, and programming of, the EEPROM. The power-up default values for all control registers are stored within
the on-chip EEPROM, and any of these EEPROM values may be changed through the serial interface
