The SC4250 is a negative voltage hotswap controller that allows the insertion of line cards into a live backplane.

The inrush current is programmable, and the closed loop operation limits the maximum current even under short circuit conditions.

A built-in timing circuit prevents false shutdown.

Programmable slew of the inrush current when used for hot insertion in the negative 24V and 48V backplane Closed loop operation limits the maximum current even in short circuit condition Built in timer prevents false shutdown when the closed loop operation limits the current Sensing the drain voltage allows for immediate shutdown in short circuit conditions where current spikes and noise are ignored Power good signal Input UVLO and OVLO sensing Circuit breaker and retry SO-8 pack.
