Overview

The FPF1038 advanced load management switch targets applications requiring a highly integrated solution for disconnecting loads powered from DC Power Rail (<6V) with stringent shutdown current targets and high load capacitances (up to 200 µF). The FPF1038 consists of slew-rate controlled low-impedance MOSFET switch (21 mΩ typical) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush-current and the resulting excessive voltage droop on power rails.
This device has exceptionally low shutdown current drain (<1 µA maximum) that facilitate compliance in very low standby power applications. The input voltage range operates from 1.2 V to 5.5 V DC to fulfill 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/GPIO with no external pull-up required. The device is packaged in advanced fully "green" 1 mm x 1.5 mm Wafer-Level Chip-Scale Packaging (WLCSP); providing excellent thermal conductivity, small footprint, and low electrical resistance for wider application usage.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
