General Description

AOZ18101DI-03/04 is a current-limiting over-voltage

protection Efuse 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 programable

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-03/04 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.

AOZ18101DI-03 is auto-restart version after fault condition.

AOZ18101DI-04 is latch-off version after fault is detected.

Both are available in small 3 mm x 3 mm 10-pin DFN package.
