General Description

The AOZ1353DI is a current-limited load 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 80μA. The supply current reduces

to less than 1μA in shut- down. It also has under-voltage

lockout (UVLO), over- voltage protection (OVP) and thermal

shutdown protection.

The AOZ1353DI 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 de-activated.

The AOZ1353DI is available in 3mm x 3mm DFN-12L

package.
