ENA2307 STK672-432BN-E Thick-Film Hybrid IC 2-phase Stepper Motor Driver http://onsemi. 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.
STK672-432BN-E Key Features
- Built-in motor terminal open detection function, overcurrent detection function, overheat detection function (output cur
- FAULT1 signal (active low) is output when any of motor terminal open, overcurrent or overheat is detected. The FAULT2 s
- 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 (0.152Ω: resistor tolerance 2%), motor current can be set using two
- The ENABLE pin can be used to cut output current while maintaining the excitation mode
- With a wide current setting range, power consumption can be reduced during standby.
