Product Description

Microstepping Driver with Translator
The A3967 is a complete microstepping motor driver with built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 30 V and ±750 mA. The A3967SLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.
FEATURES
■ ±750 mA, 30 V Output Rating
■ Satlington™ Sink Drivers
■ Automatic Current-Decay Mode Detection/Selection
■ 3.0 V to 5.5 V Logic Supply Voltage Range
