FPF1048 IntelliMAX™ 3 A-Capable, Slew-Rate-Controlled Load Switch with True Reverse Current Blocking Features Description The FPF1048 advanced load management switch targets applications requiring a highly integrated solution. It disconnects loads powered from the DC power rail (<6 V) with stringent off-state current targets and high load capacitances (up to 100 µF). The FPF1048 consists of slew-rate controlled lowimpedance MOSFET switch (23 mΩ typical) and integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. Input Voltage Operating Range: 1.5 V to 5.5 V Typical RDS(ON): - 21 mΩ at VIN=5.5 V - 23 mΩ at VIN=4.5 V - 41 mΩ at VIN=1.8 V - 90 mΩ at VIN=1.5 V Slew Rate/Inrush Control with tR: 2.7 ms (Typ.) ESD Protected: - Human Body Model: >8 kV 3 A Maximum Continuous Current Capability The FPF1048 has a True Reverse Current Blocking (TRCB) function that obstructs unwanted reverse current from VOUT to VIN during both ON and OFF states. The exceptionally low off-state current drain (<1µA maximum) facilitates compliance with standby power requirements. The input voltage range operates from 1.5 V to 5.5 VDC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial-device power management. Switch control is managed by a logic input (active HIGH) capable of interfacing directly with low-voltage control signal / General-Purpose Input / Output (GPIO) without an external pull-down resistor. Low Off Switch Current: <1 µA True Reverse Current Blocking (TRCB) Logic CMOS IO Meets JESD76 Standard for GPIO Interface and Related Power Supply Requirements - Charged Device Model: >1.5 kV - IEC 61000-4-2 Air Discharge: >15 kV - IEC 61000-4-2 Contact Discharge: >8 kV The device is packaged in advanced, fully “green” compliant, 1.0 mm x 1.5 mm, Wafer-Level Chip-Scale Package (WLCSP) with backside lamination.
