Overview
The STK672-110-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 0.22Ω current detection resistor is built in, a
current of 1A is set for each 0.22V 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 1.8A at Tc = 105°C, and of up to 2.65A at Tc = 25°C.
