STK672-640CN-E Key Features
- Built-in motor terminal open detection function(output current OFF). There is a terminal to coordinate motor terminal op
- Built-in 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 s
- 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
- 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
