Anwendungshinweise
- Full-Scale Current Adjustment Using a Digital-to-Analog Converter (DAC)PDF, 1.6 Mb, Datei veröffentlicht: Mar 10, 2017
The ability to dynamically control current in an inductive load system is very important for stepper motor designs where different levels of torque control are desired. This adjustment feature can also be used to improve system efficiency by reducing the motor current in low-load situations, achieving a longer battery life.This application report is provided as a supplement t
