MP5022A 12V Hot Swap Voltage Controller

Monolithic Power Systems MP5022A 12V Hot Swap Voltage Controller is designed to protect circuitry on the output from transients on the input. MP5022A also protects input from undesired shorts and transients coming from the output. The maximum load at the output is current limited through a sense FET topology. The magnitude of the current limit is controlled by a low-power resistor from the ISET pin to ground. An internal charge pump drives the gate of the power device, allowing for a power FET with a very low ON resistance of 3mΩ.
