LTC4234

20A Guaranteed SOA

Hot Swap Controller

FEATURES

DESCRIPTION

The LTC^®4234 is an integrated solution for Hot Swap™

applications that allows a board to be safely inserted and

removed from a live backplane. The part integrates a

Hot Swap controller, power MOSFET and current sense

resistor in a single package for small form factor applica-

tions.TheMOSFETSafeOperatingAreaisproductiontested

and guaranteed for the stresses in Hot Swap applications.

Allows Safe Board Insertion into Live Backplane

Small Footprint

4mΩ MOSFET Including R

SENSE

Safe Operating Area Guaranteed at 81W, 30ms

Wide Operating Voltage Range: 2.9V to 15V

Adjustable, 11% Accurate Current Limit

Current and Temperature Monitor Outputs

Overtemperature Protection

Adjustable Current Limit Timer Before Fault

Power Good and Fault Outputs

Adjustable Inrush Current Control

2.5% Accurate Undervoltage and Overvoltage Protection

Pin Compatible with LTC4233

The LTC4234 provides separate inrush current control

and an 11% accurate 22.5A current limit with output

dependent foldback. The current limit threshold can be

adjusteddynamicallyusingtheI pin.Additionalfeatures

SET

include a current monitor output that amplifies the sense

resistor voltage for ground referenced current sensing
