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.
