MP5010ADQ-LF-Z

MP5010A 3V-18V, 1A-5A Programmable-CurrentLimit Switch with Over-Voltage Clamp The Future of Analog IC Technology DESCRIPTION The MP5010A is a protection device designed to protect circuitry on the output (source) from transients on the input (VCC). It also protects the input from undesired shorts and transients coming from the source. A small capacitor on the dv/dt pin controls the slew rate that limit the inrush current at the source. For instance, a 1nF capacitor results in a source ramp-up time of 3ms. The maximum load at the source is current limited using a sense FET topology. An external resistor between the I-Limit pin and the Source pins 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 just 40mΩ. The MP5010A also protects the source from the input being too low or too high. Under-voltage lockout ensures that the input remains above the minimum operating threshold before the power device turns on. If the input rises above the high output threshold, the MP5010A limits the source voltage.

Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. Reduce 0.2 Watts for every 10oC ambient temperature increasing 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7 4-layer board.
