DESCRIPTION

The MPQ5074 provides up to 3A of load current

(ILOAD) across a 1.2V to 5.5V input voltage (VIN)

range. The low on resistance (RDS(ON)) and tiny

package make the MPQ5074 a highly efficient

and space-saving solution for automotive

infotainment systems, clusters, and advanced

driver-assistance systems (ADAS).

The MPQ5074 employs soft start (SS) to reduce

inrush current during circuit start up. It also

features a configurable soft-start time (tSS),

output discharge, over-current protection (OCP)

and thermal shutdown.

The maximum ILOAD at the output (source) is

current-limited by the sense FET topology. The

current limit (ILIMIT) magnitude is controlled by an

external resistor connected between the ILIM pin

and ground.

An internal charge pump drives the power

device’s gate, allowing for a 10mΩ low-RDS(ON)

DMOS power MOSFET.

The MPQ5074 is available in a tiny QFN-13

(2.5mmx3mm) package.
