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).
