MP5014A - Programmable Current-Limit Switch

General Description

The MP5014A is a protection device designed to protect circuitry on the output (source) from transients on the input (VCC).

Also, it protects VCC from undesired shorts and transients coming from the source.

At start-up, the inrush current is limited by restricting the slew rate at the source.

The Future of Analog IC Technology MP5014A 12 V, 5 A, Programmable Current-Limit Switch with Over-Volatge Clamp and Slew-Rate Control in TSOT23-8 DESCRIPTION The MP5014A is a protection device designed to protect circuitry on the output (source) from transients on the input (VCC). Also, it protects VCC from undesired shorts and transients coming from the source. At start-up, the inrush current is limited by restricting the slew rate at the source. The slew rate is controlled by a small capacitor at DV/DT. DV/DT has an internal circuit that allows this pin to float (no connection) and still receive 1 ms ramp time at the source. The maximum load at the output is current limited. This is accomplished by utilizing a sense FET topology.
