LTC4224-1/LTC4224-2

Compact Dual Low

Voltage Hot Swap Controller

FEATURES

DESCRIPTION

The LTC^®4224 Dual Low Voltage Hot Swap™ controller

allows a board to be safely inserted and removed from a

live backplane. It controls two supplies with external N-

channel MOSFETs and operates with one supply as low

as 1V provided the other supply is 2.7V or greater. The

LTC4224 can ramp up the supplies in any order and at

adjustable ramp rates. To minimize the number of external

components and PCB area, the gate capacitor is optional,

all timing delays are generated internally, and the ON pins

have integrated pull-up currents.

Allows Safe Board Insertion and Removal from a

Live Backplane

Controls Load Voltages from 1V to 6V

No Gate Components Required

Adjustable Current Limit with Circuit Breaker

Limits Peak Fault Current in ≤1μs

No External Timing Capacitor Required

Adjustable Supply Voltage Power-Up Rate
