Description
The A3966 is designed to drive both windings of a two-phase
bipolar stepper motor. The device includes two full-bridges
capable of continuous output currents of ±650 mAand 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 user selection of a reference voltage and current-sensing
resistors.
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 full-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.
For each bridge, a PHASE input controls load-current polarity
by selecting the appropriate source and sink driver pair. For
