MP5010A
3V-18V, 1A-5A Programmable-Current-
Limit 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 (V
CC
). 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 40m .
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.
