STK672-640A-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver

STK672-640A-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver
Product Detailed
STK672-640A-E 1>global presence 2>fast delivery 3>sample offering 4>long-term supply



The STK672-640A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.


> Office photocopiers, printers, etc.


> 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 resistors.

> 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.

> No motor sound is generated during hold mode due to external excitation current control.
