TPS25944ARVCR Description
The TPS25944ARVCR eFuse Power MUX is a small, feature-rich power management device with a comprehensive set of protective features. Many common DC bus voltages can be controlled thanks to the wide operating range. Bidirectional current control is provided via integrated back-to-back FETs, making the device ideal for power muxing and systems with numerous power sources.
Many programmable capabilities are available for load, source, and device protection. Undervoltage, overvoltage, overcurrent, dVo/dt ramp rate, power good, and in-rush current protection thresholds can all be customized to meet individual system needs. The device outputs PGOOD, FLT, and exact current monitor for system status monitoring and downstream load control.
When V(IN) (V(OUT) - 10 mV), the TPS25944ARVCR monitors V(IN) and V(OUT) to provide true reverse blocking from the output. The TPS25944ARVCR can be configured to assign Main/Auxiliary supply priority using the FLT and DMODE pins.
