STK672-630CN-E

Thick-Film Hybrid IC

2-phase Stepper Motor Driver

http://onsemi.com

Overview

The STK672-630CN-E is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control.

Applications

 Office photocopiers, printers, etc.

Features

 Built-in motor terminal open detection function(output current OFF).

There is a terminal to coordinate motor terminal open detection current. 

 Built-in overcurrent detection function, overheat detection function (output current OFF).

 FAULT1 signal (active low) is output when any of motor terminal open, overcurrent or overheat is detected.

The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.

 Built-in power on reset function.

 The motor speed is controlled by the frequency of an external clock signal.

 2 phase or 1-2 phase excitation switching function.

 Using either or both edges of the clock signal switching function.

Phase is maintained even when the excitation mode is switched.

 Rotational direction switching function.

 Supports schmitt input for 2.5V high level input.

 Incorporating a current detection resistor (0.141Ω: resistor tolerance 2%), motor current can be set using two

external resistors.

 The ENABLE pin can be used to cut output current while maintaining the excitation mode.

 With a wide current setting range, power consumption can be reduced during standby.

 No motor sound is generated during hold mode due to external excitation current control.

 Supports compatible pins with STK672-640CN-E.
