General Description

The AOZ1356LI is a current-limiting protection switch

targeting applications that require comprehensive protections.

For AOZ1356LI-01 and -02 the input operating

voltage range is 3.4V to 5.5V, and for AOZ1356LI-

05 and -06, the input operating voltage range is

between 3.6V and 5.3V. 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

internal soft-start circuit controls inrush current due to

highly capacitive loads. The device features very low

quiescent current. The supply current reduces to 6μA

in shut-down. It also has under-voltage lockout

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

shutdown protection.

The AOZ1356LI has True Reverse-Current Blocking

(TRCB) protection to avoid undesired reverse-current

from VOUT to VIN.

The AOZ1356LI supports USB PD Fast Role Swap.

When FON pin is high, the device is in fast turn-on

mode to ensure output voltage rises quickly to meet

USB PD spec. The device also features fast recovery

to turn on power switch once reverse current blocking

protection is de-activated.

The AOZ1356LI is available in 1.31mm x 1.81mm

WLCP package with 0.4mm pitch and 12-bumps.
