STK672-432A-E
Overview
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
The STK672-432A-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 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 FAULT1 signal (active low) is output. 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...
