The TPS25940x-Q1 eFuse Power Switches are compact,feature rich power management devices with a full suite of protection functions. The wide operatingrange allows control of many popular DC bus voltages. Integrated back-to-back FETs providebidirectional current control making the device well suited for systems with load side holdupenergy that must not drain back to a failed supply bus.

Load, source and device protection are provided with many programmable features includingovercurrent, dVo/dt ramp and overvoltage, undervoltage thresholds. Forsystem status monitoring and downstream load control, the device provides PGOOD,FLT and precise current monitor output. Precise programmable undervoltage,overvoltage thresholds and mode simplify power management design.

The TPS25940x-Q1 monitor V(IN) and V(OUT)to provide true reverse current blocking when V(IN) <(V(OUT) – 66 mV). This function supports supply bus protection fromover-voltages during output short to battery faults.
