The A3964SLBTR from Allegro Microsystems is a versatile dual full-bridge PWM motor driver IC. It is engineered for precise current control of bipolar stepper motors, capable of handling continuous output currents of up to ±800 mA and operating voltages up to 30V.
This driver integrates PWM current control circuitry, saturated sink drivers, and internal protection features including thermal shutdown, transient suppression diodes, and crossover-current protection. An internal 2.5V precision voltage reference aids in accurate motor peak-current control. The peak load current is user-settable via external resistors, and the fixed off-time pulse duration is determined by external RC timing networks.
The A3964SLBTR is supplied in a 20-pin SOIC package with internally fused pins for enhanced thermal dissipation. It features surface mount mounting type and a parallel interface for control. This component is suitable for general-purpose applications requiring bipolar stepper motor control.
