Description
AI
The MTS62C19A motor driver is an integrated circuit able to drive both windings of a bipolar stepper motor or bi-directionally control two DC motors. The two output bridges can sustain 40 V and deliver up to 750 mA of continuous current each. The maximum output current, controlled by a PWM circuit, is determined by the user’s selection of a reference voltage, a sensing resistor and two logic inputs. The outputs have been optimized for a low output saturation voltage drop.
