Overview
Description
The TPS2390 and TPS2391 are integrated circuits designed for use in -48V systems. They can withstand voltage spikes up to -100V and are 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, which can be 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 TPS2390 latches off in response to current faults, while the TPS2391 periodically retries the load in the event of a fault.

Features
Wide input supply range: -36V to -80V
Transient rating to -100V
Programmable current limit
Programmable current slew rate
Enable input (EN)
Fault timer to eliminate nuisance trips
Open-drain fault output (FAULT)
Requires few external components
8-pin MSOP package

Applications
-48V distributed power systems
Central office switching
Wireless base station
