DUAL FULL-BRIDGE PWM MOTOR DRIVER
●The A2919SB and A2919SLB motor drivers are 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).
●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
