Hardware Configuration

PWRHLD and PWREN must be connected together in CMI 111. They can be connected to VIN or to a microprocessor

output.

GPIO1 can be connected to OUT13, or it can be connected to a microprocessor output.

Startup

The ACT8846QM111-T automatically turns on OUT13 when power is applied. Pulling PWREN and PWRHLD high

enables the turn on sequencing, but does not actually start the sequencing. Pulling GPIO1 high starts the turn on

sequencing for OUT2/7/1/11/3/8/10/9. After these outputs are on, the processor can turn OUT4/5/6/12 on and off via

I2C. Note that PWREN must be high for I2C of OUT4/5/6/12.
