STK672-740A-E Datasheet PDF - ON Semiconductor

●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.
