Description
The FPF2290 features a low-RON internal FET and an
operating voltage range of 2.5 V to 23 V. An internal
clamping circuit is capable of shunting surge voltages of
±100 V, protecting downstream components and
enhancing system robustness. The FPF2290 features
over-voltage protection that powers down the internal
FET if the input voltage exceeds the OVP threshold.
The OVP threshold is selectable via Logic select pins
(OV1 and OV2). Over-temperature protection also
powers down the device at 130°C (typical).
The FPF2290 is available in a fully “green” compliant
1.3 mm × 1.8 mm Wafer-Level Chip-Scale Package
(WLCSP) with backside laminate.
