FPF2280: Over-Voltage Protection Load Switch

The FPF2280 features a low-RON internal FET and an operating range of 2.5 VDC to 5.5 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 FPF2280 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 FPF2280 is available in a fully “green” compliant 1.3 mm × 1.8 mm Wafer-Level Chip-Scale Package (WLCSP) with backside laminate.
