STK672-632AN-E Description
ENA2297 STK672-632AN-E Thick-Film Hybrid IC 2-phase Stepper Motor Driver http://onsemi. Overview The STK672-632AN-E is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control. Applications Office photocopiers, printers, etc.
STK672-632AN-E Key Features
- Built-in overcurrent detection function, overheat detection function (output current OFF)
- FAULT signal (active low) is output when overcurrent or overheat is detected
- 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
- Phase is maintained even when the excitation mode is switched
- Rotational direction switching function
- Supports schmitt input for 2.5V high level input
- Incorporating a current detection resistor (0.141Ω: resistor tolerance 2%), motor current can be set using two
- The ENABLE pin can be used to cut output current while maintaining the excitation mode
