General Description

The AOZ1328DI power switch is intended for

applications that require circuit protections. The input

operating voltage ranges between 3.4V and 22V, making

it ideal for USB Type-C power delivery applications. The

VIN terminal is rated as 28V Absolute Maximum. The

AOZ1328DI provides under-voltage lockout, over-voltage

and over-temperature protection function. The overvoltage

protection threshold is selectable through the

POVP pin. The internal soft-start

circuitry controls inrush current due to highly capacitive

loads. The slew rate can be adjusted using an external

capacitor.

The AOZ1328DI has True Reverse Current Blocking

(TRCB) protection to avoid undesired reverse-current

from VOUT to VIN at all time.

The AOZ1328DI is available in a thermally enhanced

3mm x 3mm DFN-12 package which can operate over

-40°C to +125°C junction temperature range.
