STK672-640A-E
Overview
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
The STK672-640A-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 FAULT signal (active low) is output.
- 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 input.
- Incorporating a current detection resistor (0.089Ω: resistor tolerance ±2%), motor current can be set using two external...
