The A5976GLPTR-T is a microstepping DMOS driver with an integrated translator, designed to drive bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes with a 40 V output rating and ±2.8 A output current. It is packaged in a 28-lead TSSOP with an exposed thermal pad and operates with a 3 to 5.5 V logic supply. Features include mixed, fast, and slow current decay modes, synchronous rectification for reduced power dissipation, and integrated protections against thermal shutdown, undervoltage lockout, and short circuits. The device supports automatic current decay mode selection and does not require special power-up sequencing.
Simplify stepper motor control with the A5976. The integrated translator eliminates complex microstepping programming, while selectable current decay modes and synchronous rectification ensure quiet and efficient operation.
