PT2477 Datasheet (Princeton Technology) - Micro Stepping Motor Driver

PT2477, Micro Stepping Motor Driver

The PT2477 is a monolith integrated motor driver designed for printers, scanners, and home or office automated equipment.

The dual H-bridge drivers are consisting by all of N-channel MOSFETs, and designed to drive a 4-wires bipolar stepper motor.

The output driving current of the PT2477 allows up to
