MIC2582/MIC2583
Single-Channel Hot Swap Controllers
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 over current
condition.
Datasheets and support documentation are available on
Micrel’s web site at:
