General Description

The AOZ1327DI 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 AOZ1327DI provides

under-voltage lockout, over-voltage and over-temperature

protection function. The over-voltage 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 AOZ1327DI has True Reverse-Current Blocking

(TRCB) protection to avoid undesired reverse-current from

VOUT to VIN at all time.

The AOZ1327DI is available in a thermally enhanced 3mm

x 3mm DFN-12 package which can operate over -40°C to

+85°C temperature range.
