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.
