Dual Full-Bridge PWM Motor Driver  
Features and Benefits  
Description  
±650 mA Continuous Output Current  
30 V Output Voltage Rating  
TheA3969 is designed to drive both windings of a two-phase  
bipolar stepper motor. The device includes two H-bridges  
capableofcontinuousoutputcurrentsof±650mAandoperating  
voltages to 30 V. Motor winding current can be controlled by  
the internal fixed-frequency, pulse-width modulated (PWM),  
current-control circuitry. The peak load current limit is set by  
the user’s selection of a reference voltage and current-sensing  
Internal Fixed-Frequency PWM Current Control  
Satlington Sink Drivers  
User-Selectable Blanking Window  
Internal Ground-Clamp and Flyback Diodes  
Internal Thermal-Shutdown Circuitry  
Crossover-Current Protection and UVLO Protection  
resistors.  
The fixed-frequency pulse duration is set by a user-selected  
external RC timing network. The capacitor in the RC timing  
networkalsodeterminesauser-selectableblankingwindowthat  
prevents false triggering of the PWM current-control circuitry  
during switching transitions.

To reduce on-chip power dissipation, the H-bridge power  
outputs have been optimized for low saturation voltages. The  
sink drivers feature the Allegro® patented Satlington® output  
structure. TheSatlingtonoutputscombinethelowvoltagedrop  
of a saturated transistor and the high peak current capability  
of a Darlington.
