Overview

The STK672-740A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.

Features

• Built-in overcurrent detection function (output current OFF).

• Built-in overheat detection function (output current OFF).

• If either overcurrent or overheat detection function is activated, the FAULT signal (active low) is output.

• Built-in power on reset function.

• Phase signal input driver activated with an active Low and incorporates a simultaneous ON prevention function.

• Supports schmitt input for 2.5V high level input.

• Incorporating a current detection resistor (0.089Ω: resistor tolerance ±2), motor current can be set using two external resistors.

• Provides the output current cutoff ENABLE pin.

Applications

• Office photocopiers, printers, etc.
