STK672-642A-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-642A-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 (0.089Ω: 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.
• Miniature package (provides pin compatibility with STK672-640A-E)
