STK672-640C-E
Overview
The STK672-640C-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
- Built-in opened motor pin detection function (output current OFF).
- Built-in overcurrent detection function (output current OFF).
- Built-in overheat detection function (output current OFF).
- If opened motor pin, over-current, or overheat detection function is activated, the FAULT1 signal (active low) is output. The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.
- 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...
