LT LTC4224IMS-2#PBF

热插拔控制器2自动重试，故障超时，UVLO

Overview

The LTC4224IMS-1 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 LTC4224IMS-1 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.

Protection against overcurrent faults is provided by a fast-acting current limit and timed circuit breakers. A FAULT pin signals overcurrent faults. The LTC4224-1 remains off after a fault, while the LTC4224-2 automatically tries to apply power again after a four second cool-down period.
