STK672-432AN-E  
Thick-Film Hybrid IC  
2-phase Stepper Motor Driver  
http://onsemi.com  
Overview  
The STK672-432AN-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 overcurrent detection function, overheat detection function (output current OFF).  
FAULT1 signal (active low) is output when overcurrent or overheat is detected.  
The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 levels.  
Built-in power on reset function.  
A micro-step sine wave-driven driver can be activated merely by inputting an external clock.  
External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.  
The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the  
rise and fall, or rise only, of CLOCK input.  
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 (0.152Ω: 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.  
PWM operation is separately excited system. As for PWM phase the constant current control  
which shifts the phase of Ach Bch.  
Supports compatible pins with STK672-430AN/-440AN/-442AN-E.
