FPF2280 Over-Voltage Protection Load Switch Features 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 130C (typical). Exceptionally low off-state current (<1 A maximum) facilitates compliance with standby power requirements. Surge Protection - IEC 61000-4-5: > 100 V Over-Voltage Protection (OVP) Over-Temperature Protection (OTP) ESD Protection - Human Body Model (HBM): > 3.5 kV - Charged Device Model (CDM): > 2 kV - IEC 61000-4-2 Air Discharge: > 15 kV - IEC 61000-4-2 Contact Discharge: > 8 kV Applications The FPF2280 is available in a fully "green" compliant 1.3 mm x 1.8 mm Wafer-Level Chip-Scale Package (WLCSP) with backside laminate.

(c) 2013 Fairchild Semiconductor Corporation FPF2280 * Rev. 1.8 (1) Recommended minimum R1 = 1 M www.fairchildsemi.com 2 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. Symbol VIN Parameter Min.
