Description
- AN4245, A single-chip design provides hot-swap control without circuit-breaker function on a single negative supply, while also allowing for adjustment of the turn-on voltage. The -5.2V, single-channel hot-swap circuit provides full startup control using a MAX4272 positive low-voltage hot-swap controller. The MAX4272 GND pin is connected to the -5.2V supply, while the IN and SENSE pins are connected to circuit ground. The MAX4272 then operates as if it were in a +5.2V circuit, except that no sense resistor is in the circuit, thus no overload circuit-breaker action is provided
