3966  
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-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 resistors.  
Except for package style and pinout, the two devices are identical.

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. The Satlington outputs combine the low  
voltage drop of a saturated transistor and the high peak current capability of a  
Darlington.

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. The A3966SLB

*Pb-based variants are being phased out of the product line. The variants cited in this  
footnote are in production but have been determined to be LAST TIME BUY. This  
classification indicates that sale of this device is currently restricted to existing customer  
applications. The variants should not be purchased for new design applications because  
obsolescence in the near future is probable. Samples are no longer available. Status  
change: October 31, 2006. Deadline for receipt fo LAST TIME BUY orders: April 27, 2007.
