General Description

The AOZ1356DI is a current-limiting protection switch

targeting applications that require comprehensive

protections. For AOZ1356DI-01 and -02 the input

operating voltage range is 3.4V to 5.5V, and for

AOZ1356DI-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 currentlimiting

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 AOZ1356DI has True Reverse-Current Blocking

(TRCB) protection to avoid undesired reverse-current

from VOUT to VIN.

The AOZ1356DI 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 AOZ1356DI is available in 3mm x 3mm 12-Pin DFN

package.
