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.
