The Future of Analog IC Technology
5 V, 5 A Programmable Current-Limit
Switch with Over-Voltage Clamp and
Slew-Rate Control in TSOT23-8
The MP5013A is a protection device designed to
protect circuitry on the output (source) from
transients on the input (VCC). Also, it protects the
input from undesired 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.
DV/DT has an internal circuit that allows the
customer to float this pin (no connection) and still
receive 1.4 ms ramp time at the source. The
maximum load at the source is current limited
using a 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 just 36 mΩ.
The MP5013A protects the source from the input
becoming 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 MP5013A limits the source
