The TPS2398 and TPS2399 integrated circuits are hot swap power managers optimized for use in nominal −48 V systems. They incorporate an improved circuit breaker response that provides rapid protection from short circuits, while still enabling plug−ins to tolerate large transients that can be generated by the sudden switchover to a higher voltage supply. They are designed for supply voltage ranges up to −80 V, and are rated to withstand spikes to −100 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 TPS2398 latches off in response to current faults, while the TPS2399 periodically retries the load in the event of a fault.

The NTS12100EMFS is Low Forward Voltage and low leakage Trench-based Schottky Rectifier. This new technology allows low forward voltage drop without the high reverse leakage tradeoff experienced with planar schottky rectifiers. This platform also provides very stable switching characteristics over a wide temperature range and is an ideal output rectifer for switching power supplies.

The NTS12120MFS and NTS12120EMFS devices are our new Low Forward Voltage and Low Leakage Trench-based Schottky Rectifiers. This new technology allows lower forward voltage drop without the high reverse leakage tradeoff experienced with planar schottky rectifiers. This platform also provides very stable switching characteristics over a wide temperature range and is an ideal output rectifer for switching power supplies.

This device consists of a low-power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
