The TPS***0 and TPS***1 integrated circuits are hot swap power managers optimized for use in nominal **-V systems. They are designed for supply voltage ranges up to *0 V, and are rated to withstand spikes to **0 V. In conjunction with an external N-channel FET and sense resistor, they can be used to enable live insertion of plug-in cards and modules in powered systems. Both devices provide load current slew rate and peak magnitude limiting, easily programmed by sense resistor value and a single-external capacitor. They also provide single-line fault reporting, electrical isolation of faulty cards, and protection against nuisance overcurrent trips. The TPS***0 latches off in response to current faults, while the TPS***1 periodically retries the load in the event of a fault.
