AOZ1377DI-02 Datasheet | Alpha & Omega Semiconductors

AOZ1377DI-01/-02 ECPower™ 23 V 19 mΩ Smart Protection Switch Programmable Current Limit and True Reverse Current Blocking General Description AOZ1377DI is a current-limiting protection switch targeting applications that require prehensive protections. Both VIN and VOUT terminals are rated at 28V absolute maximum. The AOZ1377DI is a USB-C protection switch with a 5A/20VIN rating, capable of operating as either a sink or a source switch. There is a programable soft-start feature that controls the inrush current for highly capacitive loads. The supply current reduces to 3µA in shut-down. It also has Input Under-Voltage Lock Out (UVLO), Input Over-Voltage Protection (OVP), and Thermal Shut Down Protection (TSD). AOZ1377DI 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. Features - 28 V abs max voltage rating on VIN and VOUT pin - Typical RON: 19mΩ - Support up to 7A at operating max 23V - Programmable current limit - True Reverse-Current Blocking (TRCB) - Input Over-Voltage Protection (OVP) - Short-Circuit Protection (SCP) - Input Under-Voltage Lock Out (UVLO) - Thermal Shut Down Protection (TSD) - HBM ESD rating: ±4kV on all pins - CDM ESD rating: ±1kV - IEC 61000-4-2: ±8kV on VOUT and VIN - IEC 61000-4-5: ±40V on VOUT, No cap - IEC 62368-1:2018 (3rd Edition) - UL2367 recognition AOZ1377DI-01 will auto-restart when the fault conditions are cleared. AOZ1377DI-02 will latch the power switch off and EN must be reset to restart the device. AOZ1377DI is available in small 3mm x 3mm 10-pin DFN package. Applications - USB PD power source switch -...
