DUAL FULL-BRIDGE PWM MOTOR DRIVER  
Designed for pulse-width modulated (PWM) current control of  
bipolar stepper motors, the A3964SB and A3964SLB are capable of  
continuous output currents to ±800 mA and operating voltages to 30 V.  
Internal fixed off-time PWM current-control circuitry can be used to  
regulate the maximum load current to a desired value. An internal  
precision voltage reference is provided to improve motor peak-current  
control accuracy. The peak load current limit is set by the user’s  
selection of an external resistor divider and current-sensing resistors.

The fixed off-time pulse duration is set by user-selected external  
RC timing networks. 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 transi-  
tions. This eliminates the need for two external RC filter networks on  
the current-sensing comparator inputs.

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

ABSOLUTE MAXIMUM RATINGS  
The A3964SB is supplied in a 24-pin plastic DIP with copper heat  
sink tabs; A3964SLB is supplied in a 20-lead plastic SOIC with copper  
heat sink tabs. The power tabs are at ground potential and need no  
electrical isolation.

Always order by complete part number:  
† Fault conditions that produce excessive junction  
temperature will activate the device’s thermal shutdown  
circuitry. These conditions can be tolerated but should  
be avoided.
