特点Allows Safe Board Insertion and Removal from a Live BackplaneSystem Reset and Power Good Control OutputsProgrammable Electronic Circuit BreakerUser Programmable Supply Voltage Power-Up RateHigh Side Driver for Two External N-ChannelsControls Supply Voltages from 3V to 12VConnection Inputs Detect Board Insertion or RemovalUndervoltage LockoutPower-On Reset Input典型应用描述A programmable electronic circuit breaker protects agianst shorts. Warning signals indicate that the circuit breaker has tripped, a power failure has occurred or that the switch drivers are turned off. The reset output can be used to generate a system reset when the power cycles or a fault occurs. The two connect inputs can be used with staggered connector pins to indicate board insertion or removal. The power-on reset input can be used to cycle the board power or claer the circuit breaker.The trip point of the ground sense comparator is set at 0.1V for LTC1421 and 2.5V for LTC1421-2.5.The LTC1421/LTC1421-2.5 are available in 24-pin SO and SSOP packages.
