Single Channel Hot Swap Controllers
Final
General Description
The MIC2582 and MIC2583 are single channel positive
voltage hot swap controllers designed to allow the safe
insertion of boards into live system backplanes. The MIC2582
and MIC2583 are available in 8-pin SOIC and 16-pin QSOP
packages, respectively. Using a few external components
and by controlling the gate drive of an external N-Channel
MOSFET device, the MIC2582/83 provide inrush current
limiting and output voltage slew rate control in harsh, critical
power supply environments. Additionally, a circuit breaker
function will latch the output MOSFET off if the current limit
threshold is exceeded for a determined period. The MIC2583R
option includes an auto-restart function upon detecting an
overcurrent condition.
