A2919SB

Dual Full Bridge PWM Motor Driver 24Pin22+2Tab PDIP Bat Tube

DUAL FULL-BRIDGE PWM MOTOR DRIVER

The 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
