PT12477 Datasheet Micro Stepping Motor Driver

Manufacturer: PTC

Overview: PT12477 45V/1.6A, Micro Stepping Motor Driver.

Datasheet Details

The PT12477 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 PT12477 allows up to 1.6 Amps (mounted on dual layer PCB with proper heatsinking, VM=24V, TA=25°C).

Automotive AEC-Q100 Grade 1 (-40℃~+125℃) Qualified.
7.4-V to 45-V supply voltage range.
1.6-A maximum driving current at VM=24V (with additional heatsink).
Dual H-bridge driver for bipolar stepper motor with such features: - PWM chopping constant current regulation - Built-In micro stepping sequencer - Multiple micro steps, Full, 1/2, 1/4, 1/8, 1/16 and up to 1/32 steps.
STEP and DIR logic inputs can control stepping motor revs and direction.
Winding current deca.
