DC628A

DC628A demonstration circuit is a single channel 5V hot swap controller featuring the LTC®4210. The LTC®4210 is a 6-pin SOT-23 Hot Swap™ controller that allows a board to be safely inserted and removed from a live back plane. An internal high side switch driver controls the GATE of an external N channel MOSFET with 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 chip on and off and is also used for the reset function.

• 6A maximum output current at ILIMIT< (VCB/RSENSE)
• 2.6V (logic high voltage-on) and 160mV (VONHYST) on/off control
