STK672-432BN-E
Overview
The STK672-432BN-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 motor terminal open detection function, overcurrent detection function, overheat detection function (output current OFF).
- FAULT1 signal (active low) is output when any of motor terminal open, overcurrent or overheat is detected. The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 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...
