STK672-630C-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
Overview
The STK672-630C-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 opened motor pin detection function (output current OFF).
• Built-in overcurrent detection function (output current OFF).
• Built-in overheat detection function (output current OFF).
• If opened motor pin, over-current, or overheat detection function is activated, the FAULT1 signal (active low) is
output. The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.
• 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 (0.141Ω: 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.
