The Future of Analog IC Technology DESCRIPTION The MP5013E is a protection device designed to protect circuitry on the output (source) from transients on the input (VCC). It also protects the input from unwanted shorts and transients coming from the source. A small capacitor on DV/DT controls the slew rate that limits the inrush current at the source. An internal circuit in DV/DT allows it to be floated (no connection) and still receive 1.2ms of ramp time at the source. The maximum load at the source is current-limited using sense FET topology. An external resistor between I-Limit and SOURCE controls the magnitude of the current limit. An internal charge pump drives the gate of the power device, allowing the DMOS power FET to have a very low on resistance of only 36mΩ.
