kr Ordering number : ENA1588A STK672-632A-E Overview Thick-Film Hybrid IC 2-phase Stepping Motor Driver The STK672-632A-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.
