Product Details
MPQ5073GG-AEC1-Z - MPS 5.5V, 2A Automotive Load Switch with Programmable Current Limit
The MPQ5073GG-AEC1-Z is an AEC-Q100 qualified 5.5V, 2A load switch from Monolithic Power Systems (MPS). Featuring an integrated low-RDS(ON) power FET, programmable current limiting, adjustable soft-start, output discharge, and fast short-circuit protection, the device provides efficient and reliable load protection for automotive and industrial electronics. Packaged in a compact QFN-12 (2mm × 2mm) package, the MPQ5073GG-AEC1-Z is well suited for space-constrained power distribution and protected load-switching applications.
Product Overview
The MPQ5073GG-AEC1-Z is designed to provide up to 2A load protection across a 0.5V to 5.5V input voltage range. An integrated DMOS power FET provides a typical on-resistance of 50mΩ, helping reduce conduction losses while maintaining a compact system footprint. The programmable current limit is set using an external resistor connected from the ILIM pin to ground, allowing engineers to tailor overcurrent protection to the load requirements.
