DUAL FULL-BRIDGE PWM  
MOTOR DRIVER  
The A3966SA and A3966SLB are designed to drive both windings of a  
two-phase bipolar stepper motor. Each device includes two H-bridges  
capable of continuous output currents of 650 mA and operating voltages to  
30 V. Motor winding current can be controlled by the internal fixed-fre-  
quency, 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 resistors. Except for package style and pinout, the two  
devices are identical.

The fixed-frequency pulse duration is set by a user-selected external  
RC timing network. The capacitor in the RC timing network also determines  
a user-selectable blanking window that 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 Allegro’s  
patented Satlington™ output structure. The Satlington outputs combine the  
low voltage drop of a saturated transistor and the high peak current capability  
of a Darlington.

For each bridge, a PHASE input controls load-current polarity by  
selecting the appropriate source and sink driver pair. For each bridge, an  
ENABLE input, when held high, disables the output drivers. Special power-  
up sequencing is not required. Internal circuit protection includes thermal  
shutdown with hysteresis, ground-clamp and flyback diodes, and crossover-  
current protection.

The A3966SA is supplied in a 16-pin dual in-line plastic package. The  
A3966SLB is supplied in a 16-lead plastic SOIC with copper heat sink tabs.  
The power tab is at ground potential and needs no electrical isolation.
