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.

network. The capacitor in the RC timing network also determines a user-

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. 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.

These variants include: A3966SA, A3966SLB, and A3966SLBTR.
