AMT49700 provides single step control with an adjustable microstep resolution for fine positioning and programmable motion control.
Designed for pulse-width-modulated (PWM) control of DC motors, the A4955 is capable of 50 V operation and provides gate drive for an all n-channel external MOSFET bridge.
This report outlines hot-swap test results for A5977 and A5979 stepper motor drivers. To duplicate the hot-swap conditions, we have selected an IC motor supply voltage (VBB) of 24 V and motor current of 1.5 A per winding for our tests.了解更多
Many applications require reliable detection of reaching a mechanical endpoint without using an external sensor, and motor stall detection can be used instead. This article describes an innovative method of small stepper motor stall detection and its application.了解更多
