ECPowerTM 23 V 36 mΩ Protection Switch Programmable Current Limit and True Reverse Current Blocking General Description Features
AOZ1374DI is a current-limiting protection switch targeting
•
28 V abs max voltage rating on VIN and VOUT pin applications that require comprehensive protections.
•
Typical R Both VIN and VOUT terminals are rated at 28 V absolute ON: 36 m Ω
•
Programmable current limit maximum. There is a programable soft-start feature up to 10ms to limit the inrush current for highly capacitive loads.
•
True Reverse Current Blocking (TRCB) The supply current reduces to 5 µ A in shutdown. It also has
•
Input Over-Voltage Protection (OVP) Input Under-Voltage Lock Out (UVLO), Input Over-Voltage
•
Short-Circuit Protection (SCP) Protection (OVP), and Thermal Shut Down Protection (TSD).
•
Input Under-Voltage Lock Out (UVLO) AOZ1374DI has True Reverse Current Blocking (TRCB)
•
Thermal Shut Down Protection (TSD) protection to avoid undesired reverse-current from VOUT to
•
HBM ESD rating: ±4 k V on all pins VIN. It also features an internal current-limiting circuit that
•
CDM ESD rating: ±1 k V protects the supply from large load current. The current limit
•
IEC 61000-4-2: ±8 k V on VOUT threshold can be set externally with a resistor.
•
IEC 61000-4-5: 45 V on VOUT, no cap AOZ1374DI-01 will auto-restart when the fault conditions
