General Description

The AOZ1353LI is a current-limited power switch targeting

applications that require comprehensive protections.

The input operating voltage range is between 3.4V and

5.5V. The output terminal is rated 28V absolute maximum.

The internal current-limiting circuit protects the

supply from large load current. The current limit level is

set with an external resistor. The soft-start circuit controls

inrush current due to highly capacitive loads. The

soft-start time can be optionally adjusted with an external

capacitor. The device features very low quiescent

current of 125μA. The supply current reduces 6μA in

shutdown. It also has under-voltage lockout (UVLO),

over-voltage protection (OVP) and thermal shutdown

protection.

The AOZ1353LI has True Reverse-Current Blocking

(TRCB) protection to avoid undesired reverse-current

from VOUT to VIN.

The device features fast recovery to turn on power

switch once reverse current blocking protection is deactivated.

The AOZ1353LI is available in a 1.31mm x 1.81mm

Wafer-Level Chip-Scale Package (WLCSP with 12

bumps).
