TPS25942ARVCR Description
TPS25942ARVCR eFuse Power MUX are compact and feature-rich power management devices with a full set of protection functions. The wide operating range allows the control of many popular DC bus voltages. The integrated back-to-back FET provides bi-directional current control, making the device ideal for power multiplexing and systems with multiple power supplies. Load, power, and device protection have many programmable functions. The thresholds for undervoltage, overvoltage, overcurrent, DVO/DT slope, good power supply and inrush current protection are all programmable to meet specific system requirements. For system condition monitoring and downstream load control, the device provides PGOOD, FLT and accurate current monitoring output. TPS25942 and TPS25944 monitor V (IN) and V (OUT) to provide true reverse blocking output when V (IN) < (V (OUT)-10 mV). The device can be configured to assign primary / auxiliary power priority using FLT and DMODE pins.
