MIC2595

MIC2589/2595 Micrel MIC2589/MIC2595 Single-Channel, Negative High-Voltage Hot Swap Power Controllers/Sequencers General Description Features The MIC2589 and MIC2595 are single-channel, negative Provides safe insertion and removal from live voltage hot swap controllers designed to address the need for –48V (nominal) backplanes safe insertion and removal of circuit boards into “live” system Operates from –19V to –80V backplanes, while using few external components. The Fast responding circuit breaker (<1µs) to short circuit MIC2589/89R and the MIC2595/95R are each available in conditions 14-pin SOIC packaging and work in conjunction with an User-programmable overcurrent detector response time external N-Channel MOSFET for which the gate drive is Electronic circuit breaker function: controlled to provide inrush current limiting and output voltOutput latch OFF (MIC2589/95) or age slew-rate control. Overcurrent fault protection is also Output auto-retry (MIC2589R/95R) provided for which the overcurrent threshold and the Active current regulation precisely controls inrush overcurrent duration are programmable. Very fast fault recurrents sponse is provided to ensure that system power supplies Regulated maximum output currents into faults maintain regulation even during output short circuits. This Programmable undervoltage and overvoltage lockouts family offers two responses to a circuit breaker fault condition: (MIC2589/89R) the MIC2589 and MIC2595 latch the circ...
