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. STK672-120-SL-E Overview The STK672-120-SL-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 • The motor speed can be controlled by the frequency of an external clock signal (the CLOCK pin signal). • The excitation type is switched according to the state (low or high) of the MODE pin. The mode is set to 2-phase or 1-2phase excitation on the rising edge of the clock signal. • A motor direction switching pin (the CWB pin) is provided. • All inputs are schmitt inputs and 40kΩ (typical: –50 to +100%) pull-up resistors are built in. • The motor current can be set by changing the Vref pin voltage. Since a 0.165Ω current detection resistor is built in, a current of 1A is set for each 0.165V of applied voltage. • The input frequency range for the clock signal used for motor speed control is 0 to 25kHz. • Supply voltage ranges: VCC = 10 to 42V, VDD = 5.0V ±5% • This IC supports motor operating currents of up to 2.4A at Tc = 105°C, and of up to 4.0A at Tc = 25°C.
