Microchip Technology MIC2589-2YM

Description
The MIC2589 and MIC2595 are single-channel, negative voltage hot swap controllers designed for safe insertion and removal of circuit boards into live system backplanes. They operate from -19V to -80V and work in conjunction with an external N-Channel MOSFET to provide inrush current limiting and output voltage slew-rate control. Overcurrent fault protection is provided via a programmable overcurrent threshold and filter. Fast fault response ensures system power supplies maintain regulation during output short circuits.

Features
Safe insertion and removal from live -48V backplanes
Fast responding circuit breaker (<1μs) to short circuit conditions
User-programmable overcurrent detector response time
Electronic circuit breaker function:
Output latch OFF (MIC2589/MIC2595)
