STK672-440AN-E
Overview
The STK672-440AN-E is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control.
Applications
- Office photocopiers, printers, etc.
Features
- Built-in overcurrent detection function, overheat detection function (output current OFF).
- FAULT1 signal (active low) is output when overcurrent or overheat is detected. The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 levels.
- Built-in power on reset function.
- A micro-step sine wave-driven driver can be activated merely by inputting an external clock.
- External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.
- The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the rise and fall, or rise only, of CLOCK input.
- Phase is maintained even when the excitation mode is switched. Rotational direction switching function.
- Supports schmitt...
