AOZ18101DI-02 Datasheet | Alpha & Omega Semiconductors

Description AOZ18101DI-01/02 is a current-limiting over-voltage protection e Fuse targeting applications that require front end protection at the input line. Both VIN and VOUT terminals are rated at 22 V absolute maximum. There is a programmable soft-start feature that controls the inrush current for highly capacitive loads. It also has Input Under-Voltage Lock Out (UVLO), Input Over-Voltage Output Clamp (OVC), and Thermal Shut Down Protection (TSD). AOZ18101DI-01/02 has built-in blocking FET for True Reverse Current Blocking (TRCB). For application flexibility, an external blocking FET control pin is also available if standalone MOSFET is preferred. 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. It will auto-restart after the fault conditions are released. AOZ18101DI-01 is auto-restart version after fault condition. AOZ18101DI-02 is latch-off version after fault is detected. Both are available in small 3 mm x 3 mm 10-pin DFN package. AOZ18101DI-01 is pin to pin patible with TPS259241. AOZ18101DI-02 is pin to pin patible with TPS259240.
