AOZ1374DI-01集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

General Description

AOZ1374DI is a current-limiting protection switch targeting

applications that require comprehensive 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.
