Hardware Configuration

PWRHLD should be connected directly to OUT13. This automatically turns on OUT12 when the always-on OUT13 turns

on after input power is applied.

PWREN should be connected to an SL3600 GPIO. Pulling PWREN high turns on OUT1/2/3/4/5. Pulling PWREN low

turns off OUT1/2/3/4/5/6/7/8/9/10/11.

Startup

The ACT8846QM109-T automatically turns on OUT13 when power is applied. Connecting the PWRHLD pin to OUT13

automatically turns on OUT12 after OUT13 turns on. A processor GPIO connected to PWREN turns on OUT1/2/3/4/5

when the GPIO goes high. After OUT12/13 are turned on, the processor can turn OUT6/7/8/9/10/11 on and off via I2C

while PWREN is held high.
