MIC2595
The MIC2589 and MIC2595 are single-channel, negative voltage hot swap controllers designed to address the need for safe insertion and removal of circuit boards into "live" system backplanes, while using few external components. The MIC2589/MIC2589R and the MIC2595/MIC2595R are each available in 14-pin SOIC packaging and work in conjunction with an external N-Channel MOSFET for which the gate drive is controlled to provide inrush current limiting and output voltage slew-rate control. Overcurrent fault protection is also provided via a programmable overcurrent threshold and filter. Very fast fault response is provided to ensure that system power supplies maintain regulation even during output short circuits. These controllers offer two responses to a circuit breaker fault condition: the MIC2589 and MIC2595 latch the circuit breaker's output off when the overcurrent threshold interval is exceeded and the overcurrent filter times out while the MIC2589R and MIC2595R automatically attempt to restart at a fixed duty cycle after a current limit fault. A primary Power-Good signal and two secondary (delayed and staggered) Power-Good signals are provided to indicate that the output voltage is within its valid operating range. These signals can be used to perform an all-at-once or a sequenced enabling of one or more DC-DC power modules.
