TIDA-01162

Integrated vs. Discrete Low Voltage Motor Drive Comparison Reference Design

TIDA-01162

Design files

Overview

TIDA-01162 demonstrates the key differences between an integrated vs. discrete low-voltage motor drive solution. The discrete solution is implemented using two large external MOSFETs, while the integrated solution utilizes TI’s DRV8850 brushed DC motor driver.  Both designs are implemented on a single PCB for a quick-comparison of the two solutions.
