The TPS25940 eFuse Power Switch is a compact, feature rich power
management device with a full suite of protection functions,
including a low power DevSleep™ mode that supports compliance with
the SATA™ Device Sleep standard. The wide operating range allows
control of many popular DC bus voltages. Integrated back to back
FETs provide bidirectional current control making the device well
suited for systems with load side holdup energy that must not drain
back to a failed supply bus. Load, source and device protection are provided with many
programmable features including overcurrent, dVo/dt ramp and overvoltage, undervoltage thresholds. For system
status monitoring and downstream load control, the device provides
PGOOD, FLT and precise current monitor output. Precise programmable
undervoltage, overvoltage thresholds and the low IQDevSleep mode simplify SSD power management design. The TPS25940 monitors V(IN) and V(OUT) to provide true reverse current blocking when V(IN) < (V(OUT) - 10 mV). This function supports swift changeover to a boosted
voltage energy storage element in systems where backup voltage is
greater than bus voltage. |
