LTC4210-4C 数据手册 ( 数据表 ) - Linear Technology

DESCRIPTION
The LTC®4210-3/LTC4210-4 is a 6-pin SOT-23 Hot SwapTM 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 7V. The LTC4210 provides the initial timing cycle and allows the GATE to be ramped up at an adjustable rate.
