ACT88430

Advanced PMU for Microcontrollers and Solid State Drive Applications

Startup

SLEEP Mode

Pull PWREN high to operate in ACTIVE mode. Pull PWREN low to operate in SLEEP mode. Buck1/4 turn off in SLEEP

mode. Buck2/3 regulate to VSET1 in SLEEP mode.

DVS Mode

This CMI does not have true DVS functionality. See the different GPIO functions to see which ones control a buck

converter’s output voltage.

POK Thresholds

POK_UV = 2.77V

POK_OV = 3.76V

The PG pin is not used and can be left open or pulled to GND.

POK

POK is configured as an input to select the Buck4 output voltage. When POK is L, VSET1 sets Buck4 to 1.2V. When

POK is H, VSET0 sets Buck1 to 1.8V.

EXT_EN

The EXT_EN pin is not used and should be left open.

nRESET

The nRESET pin is configured as the Buck2 POK open drain output with 0ms delay.

nRESET_AUX1

The nRESET_AUX1 pin is programmed as an open drain output. It goes high 1989us after Buck4 goes into regulation.
