AOZ1356LI Datasheet | Alpha & Omega Semiconductors

Description The AOZ1356LI is a current-limiting protection switch targeting applications that require prehensive protections. For AOZ1356LI-01 and -02 the input operating voltage range is 3.4V to 5.5V, and for AOZ1356LI05 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.
