Negative Voltage

Hot Swap Controllers in SOT-23

FEATURES

DESCRIPTION

The LTC^®4251/LTC4251-1/LTC4251-2 negative voltage

Hot Swap™ controllers allow a board to be safely inserted

and removed from a live backplane. Output current is con-

trolled by three stages of current limiting: a timed circuit

breaker, active current limitinganda fastfeedforwardpath

that limits peak current under worst-case catastrophic

fault conditions.

Allows Safe Board Insertion and Removal from a

Live –48V Backplane

Floating Topology Permits Very High Voltage

Operation

Programmable Analog Current Limit with Circuit

Breaker Timer

Fast Response Time Limits Peak Fault Current

Programmable Timer

Programmable undervoltage and overvoltage detectors

disconnect the load whenever the input supply exceeds

the desired operating range. The supply input is shunt

regulated, allowing safe operation with very high supply

voltages. A multifunction timer delays initial start-up and

controls the circuit breaker’s response time.

Programmable Undervoltage/Overvoltage Protection

Low Profile (1mm) ThinSOT™ Package

APPLICATIONS

Hot Board Insertion

The LTC4251 UV/OV thresholds are designed to match the

standard telecom operating range of –43V to –75V. The

LTC4251-1 UV/OV thresholds extend the operating range

to encompass –36V to –72V. The LTC4251-2 implements

a UV threshold of –43V only.

Electronic Circuit Breaker

–48V Distributed Power Systems

Negative Power Supply Control

Central Office Switching

Programmable Current Limiting Circuit

High Availability Servers

Disk Arrays

All parts are available in the 6-Pin SOT-23 package.
