Overview
MIC2588/MIC2594 Micrel MIC2588/MIC2594 Single-Channel, Negative High-Voltage Hot Swap Power Controllers General Description The MIC2588 and the MIC2594 are single-channel, negative-voltage hot swap controllers designed to address the need for safe insertion and removal of circuit boards into “live” high-voltage system backplanes, while using very few external components.
The MIC2588 and the MIC2594 are each available in an 8-pin SOIC package 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 and includes a programmable overcurrent threshold.
During an output overload condition, a constantcurrent regulation loop is engaged to ensure that the system power supply maintains regulation.
If a fault condition exceeds a built-in 400µs nuisance-trip delay, the MIC2588 and the MIC2594 will latch the circuit breaker’s output off and...
