LTC4280

Hot Swap Controller with

I C Compatible Monitoring

FEATURES

DESCRIPTION

The LTC^®4280 Hot Swap™ controller allows a board to be

safely inserted and removed from a live backplane. Using

anexternalN-channelpasstransistor,boardsupplyvoltage

and inrush current are ramped up at an adjustable rate.

Allows Safe Insertion into Live Backplane

8-Bit ADC Monitors Current and Voltage

I C/SMBus Interface

Wide Operating Voltage Range: 2.9V to 15V

Adjustable Overcurrent Filter Time

An I C interface and onboard ADC allow for monitoring

High Side Drive for External N-Channel MOSFET

of load current, voltage and fault status.

No External Gate Capacitor Required

The device features adjustable analog foldback current

limit and a FILTER pin which conﬁgures the time spent in

overcurrent before declaring a fault. An I C interface may

conﬁgure the part to latch off or automatically restart after

the LTC4280 detects a current limit fault.

Input Overvoltage/Undervoltage Protection

Optional Latchoff or Auto-Retry After Faults

Alerts Host After Faults

Inrush Current Limit with Foldback

Available in 24-Pin 4mm × 5mm QFN Package

The controller has additional features to interrupt the host

when a fault has occurred, notify when output power is

good, detect insertion of a load card, and power-up either
