Product Details
The LTC1422 is an 8-pin Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. Using an external N-channel pass transistor, the board supply voltage can be ramped up at a programmable rate. A high side switch driver controls the N-channel gate for supply voltages ranging from 2.7V to 12V.
A programmable electronic circuit breaker protects against shorts. The RESET output can be used to generate a system reset when the supply voltage falls below a programmable voltage. The ON pin can be used to cycle the board power or to generate a soft reset.
The LTC1422 is available in 8-pin PDIP and SO packages.
Applications
- Hot Board Insertion
- Electronic Circuit Breaker
