Description
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.

FPF2280 • Rev. 1.8 3
FPF2280 — Over-Voltage Protection Load Switch
On-The-Go (OTG) Functionality
During OTG operation, the FPF2280 is initially disabled
and the power FET's bulk diode is forward biased. The
bulk diode represents ~0.7 V drop across the device,
which remains until the V_IN voltage increases past
2.5 V, when the device is fully enabled. While the device
is disabled and the body diode is forward biased, the
max DC current through the diode is 1.8 A. This current
is limited by the thermal performance of the device
(0.7 Vx 1.8 A = 1.36 W). This current should be
transient; the #EN pin must be pulled LOW to ensure
the device fully enables. The transient should not
exceed the RC time constant of the C_IN and C_OUT
capacitors. At the system level, over-voltage and current
protection should be provided outside the FPF2280.
Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
