MIC2582/MIC2583

Single Channel Hot Swap Controller

Preliminary Information

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. Using few

external components, the parts act in conjunction with an

external N-Channel MOSFET device, for which the gate drive

is controlled to provide inrush current-limiting and output

voltage slew rate control. The MIC2582/3 are rated for

operation from supply voltages from 2.3V to 13.2V, but can

withstand transient voltages as high as 20V without damage.

Overcurrent fault protection is provided along with a program-

mable over-current threshold. Active current regulation dur-

ing start-up ensures that inrush current never exceeds the

programmed threshold. The MIC2582/3 provide a circuit

breaker function that latches the output MOSFET off if the

current limit threshold is exceeded for a programmed period

of time. Dual-level fault detection allows very fast response

to short-circuit faults while preventing lower level overcurrent

transients from causing “nuisance tripping” of the circuit

breaker. A /FAULT signal is provided indicating overcurrent

or undervoltage fault conditions.

Features

• Provides safe insertion and removal from live

backplanes

• 2.3V to 13V supply voltage operation

• Surge voltage protection up to 20V

• Undervoltage Lockout protection

• Programmable inrush current-limiting

• Current regulation limits inrush current regardless of

load capacitance

• Dual-level overcurrent fault sensing eliminates false

tripping

• Fast response to short circuit conditions (< 1

µs)

• Power-On Reset and Power-Good status outputs

(MIC2583)

• Programmable output undervoltage detection

• Electronic circuit breaker

• /FAULT status output

• Auto-restart function (MIC2583R)
