Basic Structure of Brushed Motor Drivers

Hybrid ICs for Driving Brush-Type DC Motors

onsemi

This presentation includes four main topics: First, the basic structure of a brushed-motor driver. Second, a description of the current flow in the driver while operating in its four states. Third, a comparison of the products to the major competitive devices. Finally, some details about the STK681 family of products, including applications and typical waveforms.
