STK672-120-SL-E Overview
ENA2140 STK672-120-SL-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi. 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.
STK672-120-SL-E Key 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
- A motor direction switching pin (the CWB pin) is provided
- The motor current can be set by changing the Vref pin voltage. Since a 0.165Ω current detection resistor is built in, a
- 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
