Description
The FPF2281 features a low-RON internal FET and an
operating range of 2.5 VDC to 25 VDC (absolute
maximum of 29 VDC). An internal clamp is capable of
shunting surge voltages >100 V, protecting downstream
components and enhancing system robustness. The
FPF2281 features over-voltage protection that powers
down the internal FET if the input voltage exceeds the
OVP threshold. The OVP threshold is adjustable with
optional external resistors. Over-temperature protection
also powers down the device at 130°C (typical).
Exceptionally low off-state current (<1 μA maximum)
facilitates compliance with standby power requirements.
The FPF2281 is available in a fully “green” compliant
1.3 mm × 1.8 mm Wafer-Level Chip-Scale Package
(WLCSP) with backside laminate.
