AOZ1374DI Datasheet | Alpha & Omega Semiconductors

Description AOZ1374DI is a current-limiting protection switch targeting applications that require prehensive protections. Both VIN and VOUT terminals are rated at 28 V absolute maximum. There is a programable soft-start feature up to 10ms to limit the inrush current for highly capacitive loads. The supply current reduces to 5 µ A in shutdown. It also has Input Under-Voltage Lock Out (UVLO), Input Over-Voltage Protection (OVP), and Thermal Shut Down Protection (TSD). AOZ1374DI has True Reverse Current Blocking (TRCB) protection to avoid undesired reverse-current from VOUT to VIN. It also features an internal current-limiting circuit that protects the supply from large load current. The current limit threshold can be set externally with a resistor. AOZ1374DI-01 will auto-restart when the fault conditions are cleared. AOZ1374DI-02 will latch the power switch off in case of a fault condition and EN must be reset to restart the device. AOZ1374DI is available in small 3 mm x 3 mm 10-pin DFN package.
