5V, 2A, Programmable Current-
Limit Switch with Over-Voltage Clamp
and Slew Rate Control in a TSOT23-8
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
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.
The MP5013E protects the source from the
input being too low or too high. Under-voltage
lockout (UVLO) 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 MP5013E
limits the source voltage.
