1 / 27 page 82912HKPC 018-11-0017 No. A2116-1/27 http://onsemi.com Semiconductor Components Industries, LLC, 2013 June, 2013 STK672-640C-E Overview The STK672-640C-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 opened motor pin detection function (output current OFF). • Built-in overcurrent detection function (output current OFF). • Built-in overheat detection function (output current OFF). • If opened motor pin, over-current, or overheat detection function is activated, the FAULT1 signal (active low) is output. 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 (0.089Ω: 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.
