A2919 Overview
The A2919 motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. Both bridges are capable of sustaining 45 V and include internal pulse width modulation (PWM) control of the output current to 750 mA. The outputs have been optimized for a low output-saturation voltage drop (less than 1.8 V total source plus sink at 500 mA).
A2919 Key Features
- 750 mA continuous output current
- 45 V output sustaining voltage
- Internal clamp diodes
- Internal PWM current control
- Low output saturation voltage
- Internal thermal shutdown circuitry
- Half- or quarter-step operation of bipolar stepper motors
