STK672-642A-E Description
ENA1589A STK672-642A-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi. Overview The STK672-642A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications Office photocopiers, printers, etc.
STK672-642A-E Key Features
- Built-in overcurrent detection function (output current OFF)
- Built-in overheat detection function (output current OFF)
- If either over-current or overheat detection function is activated, the FAULT signal (active low) is output
- 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
