1 / 19 page 91212HKPC 018-08-0108 No.A0751-1/19 Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer 's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer 's products or equipment. Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment. The products mentioned herein shall not be intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee thereof. If you should intend to use our products for new introduction or other application different from current conditions on the usage of automotive device, communication device, office equipment, industrial equipment etc. , please consult with us about usage condition (temperature, operation time etc.) prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. STK672-400 Overview The STK672-400 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications • Office photocopiers, printers, etc. Features • Entry of external clock is enough to activate the micro step sinusoidal driver. • The excitation mode of 2, 1-2, W1-2, 2W1-2, or 4W1-2 can be selected with the external pin. • The 4-phase distributor switching timing can be set to occur either on both rising and falling edge detection or on rising edge detection only with an external pin (MODE3). • A phase holding function is provided to prevent phase skip during switching of excitation in the course of operation. • The motor current is set by a voltage divider formed by an external resistor connected to the Vref pin. • The CLK input pin is provided with an internal noise filtering circuit in addition to a Schmidt circuit to increase the margin for extraneous noise. • When set low, the ENABLE pin turns off the motor drive current for all phases and retains the phase excitation state.
