STK672-622A-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-622A-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 FAULT1 signal (active low) is output.
The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 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 (0.222Ω: 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.

* Operation at the maximum VCC value may not be possible, depending on the motor current. See “8. Other Notes on
Use” in the Data Sheet for details.
*Ioave values are for when the lead frame of the product is soldered to the mounting substrate.
Notes: A fixed-voltage power supply must be used.

Notes
The current range given above represents conditions when output voltage is not in the avalanche state.
If the output voltage is in the avalanche state, see the allowable avalanche energy for STK672-6** series hybrid ICs given
in a separate document.
The operating substrate temperature, Tc, given above is measured while the motor is operating.
Because Tc varies depending on the ambient temperature, Ta, the value of IOH, and the continuous or intermittent
operation of IOH, always verify this value using an actual set.
The Tc temperature should be checked in the center of the metal surface of the product package.
