Capabilities With and Without Using the Serial Interface
The MSL1060/61/64 operates as standalone LED drivers with full digital (PWM) and analog (DAC) LED dimming
control and fault reporting. For the MSL1061/64, these functions are managed over the I
2
C or SMB serial interface.
This allows LED intensity control through software. The serial interface also accesses more detailed fault management
reporting as well as software controlled shutdown which turns off the LED drivers while the serial interface remains active.
