STK672-432A-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
Overview
The STK672-432A-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.
• A micro-step sine wave-driven driver can be activated merely by inputting an external clock.
• External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.
• The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the
rise and fall, or rise only, of CLOCK input.
• 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 (0.152Ω: 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.
• A external excitation system is used for PWM operations. Fixed current control for shifting the phase of Ach/Bch is
used for the PWM phase.
• Miniature package (provides pin compatibility with STK672-430A-E)

STK672-432A-E
[Vref (Voltage setting to be used for the current setting reference)]
• Pin type: Analog input configuration, input pull-down resistor 100kΩ
Input voltage is in the voltage range of 0.14V to 1.48V.
[Input timing]
The control IC of the driver is equipped with a power on reset function capable of initializing internal IC operations
when power is supplied. A 4V typ setting is used for power on reset. Because the specification for the MOSFET gate
voltage is 5V±5%, conduction of current to output at the time of power on reset adds electromotive stress to the
MOSFET due to lack of gate voltage. To prevent electromotive stress, be sure to set ENABLE=Low while VDD,
which is outside the operating supply voltage, is less than 4.75V.
In addition, if the RESETB terminal is used to initialize output timing, be sure to allow at least 10μs until CLOCK
input.
