General Description

The AOZ1373DI 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. VIN

and VOUT terminals are rated as 28V Absolute

Maximum. The AOZ1373DI provides under-voltage

lockout, over-voltage and over-temperature protection

function. The over-voltage protection threshold is

selectable by an external resistor. The internal soft-start

circuitry controls inrush current due to highly capacitive

loads. The slew rate can be adjusted using an external

capacitor.

The AOZ1373DI has True Reverse-Current Blocking

(TRCB) protection to avoid undesired reverse-current

from VOUT to VIN at all time.

The AOZ1373DI is available in a 3mm x 3mm DFN-12

package which can operate over -40°C to +85°C

temperature range.
