Monolithic Power Systems (MPS) MPQ5077A AEC-Q100 Configurable Load Switches
Monolithic Power Systems (MPS) MPQ5077A AEC-Q100 Configurable Load Switches provide up to 7A of load protection across a 1.2V to 5.5V input voltage (VIN) range. With low on-resistance [RDS(ON)] in a tiny package, the MPQ5077A offers a highly efficient, space-saving solution for automotive infotainment, clusters, and Advanced Driver-Assistance System (ADAS) applications. The soft start (SS) function avoids an inrush current during circuit start-up. MPQ5077A also provides a configurable soft-start time (tSS), output discharge functions, overcurrent protection (OCP), and thermal shutdown.
The maximum load at the output source is current-limited, accomplished using a sense MOSFET topology. The current limit magnitude is controlled by an external resistor from the ILIM pin to ground. An internal charge pump drives the power device gate, allowing a very low-RDS(ON) DMOS power MOSFET of only 10mΩ. The MPS MPQ5077A AEC-Q100 Configurable Load Switches are available in a tiny QFN-13 (2.5mm x 3mm) package.
