The is a positive high voltage, hot-swap controller in 8 pin NSOIC package. This fully integrated hot-swap controller for +9V to +80V positive supply rails, it allows for the safe insertion and removal of circuit cards into a live backplane without causing glitches on backplane power supply rail. Device is pin and function compatible to LT1641-1. It features a programmable foldback current limit. If the device remains in current limit for more than a programmable time, the external N-channel MOSFET latches off. Other features include a programmable undervoltage lockout and a programmable output-voltage slew rate through an external N-channel MOSFET. It provides a power good output PWRGD to indicate status of output voltage. It is used in hot board insertion, electronic circuit breaker, industrial high-side switch/circuit breaker, network routers and switches and 24V/48V industrial/alarm systems.
