Description

The LTC4210 is a 6-pin SOT-23 Hot Swap™controller that allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the GATE of an external N-channel MOSFET for a supply voltage ranging from 2.7V to 16.5V. The LTC4210 provides the initial timing cycle and allows the GATE to be ramped up at an adjustable rate.The LTC4210 features a fast current limit loop providing active current limiting together with a circuit breaker timer. The signal at the ON pin turns the part on and off and is also used for the reset function.This part is available in two options: the LTC4210-1 for automatic retry on overcurrent fault and the LTC4210-2 for latch off on an overcurrent fault.VinRangeRetry / LatchoffLTC4210-12.7V to 16.5VRetry After FaultLTC4210-22.7V to 16.5VLatch Off After FaultLTC4210-32.7V to 7VRetry After FaultLTC4210-42.7V to 7VLatch Off After FaultApplicationsHot Board InsertionElectronic Circuit BreakerIndustrial High Side Switch/Circuit Breaker
