.DataSheet.co.kr Ordering number : ENA1587A STK672-442A-E Overview Thick-Film Hybrid IC 2-phase Stepping Motor Driver The STK672-442A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications Office photocopiers, printers, etc.
STK672-442A-E Key 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
- Built-in power on reset function
- A micro-step sine wave-driven driver can be activated merely by inputting an external clock
- The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the ris
- 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 (0.122Ω: resistor tolerance ±2%), motor current can be set using two external
- The ENABLE pin can be used to cut output current while maintaining the excitation mode
