AOZ1353LI Datasheet | Alpha & Omega Semiconductors

Description The AOZ1353LI is a current-limited power switch targeting applications that require prehensive 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 125µA. The supply current reduces 6µA in shutdown. It also has under-voltage lockout (UVLO), over-voltage protection (OVP) and thermal shutdown protection. The AOZ1353LI 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 deactivated. The AOZ1353LI is available in a 1.31mm x 1.81mm Wafer-Level Chip-Scale Package (WLCSP with 12 bumps).
