STK672-740A-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-740A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.
Applications
Office photocopiers, printers, etc.
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.

Notes
The current range given above represents conditions when output voltage is not in the avalanche state.
If the output voltage is in the avalanche state, see the allowable avalanche energy for STK672-7** series hybrid ICs given
in a separate document.
The operating substrate temperature, Tc, given above is measured while the motor is operating.
Because Tc varies depending on the ambient temperature, Ta, the value of IOH, and the continuous or intermittent
operation of IOH, always verify this value using an actual set.
The Tc temperature should be checked in the center of the metal surface of the product package.
