General Description
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.
Key Features
- 8V to 45V supply voltage range.
- 1.6-A maximum driving current at VM=24V (with additional heatsink).
