STK672-432B-E
Thick-Film Hybrid IC
2-phase Stepping Motor Driver
http://onsemi.com
Overview
The STK672-432B-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 motor terminal open detection function (output current OFF).
Built-in overcurrent detection function (output current OFF).
Built-in overheat detection function (output current OFF).
FAULT1 signal (active low) is output when any of motor terminal open, overcurrent, or overheat is detected.
The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 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.

Precautions
[GND wiring]
To reduce noise on the 5V/24V system, be sure to place the GND of C01 in the circuit given above as close as
possible to Pin 2 and Pin 6 of the hybrid IC.
In addition, in order to set the current accurately, the GND side of RO2 of Vref must be connected to the shared
ground terminal used by the Pin 18 (S.G) GND, P.G1 and P.G2.
[Input pins]
If VDD is being applied, use care that each input pin does not apply a negative voltage less than -0.3V to S.GND,
Pin 18. Measures must also be taken so that a voltage equal to or greater than VDD is not input.
High voltage input other than VDD, MOI, FAULT1, and FAULT2 is 2.5V.
Pull-up resistors are not connected to input pins. Pull-down resistors are attached. When controlling the input to the
hybrid IC with the open collector type, be sure to connect a pull-up resistor (1 to 20kΩ).
Be sure to use a device (0.8V or less, low level, when IOL=5mA) for the open collector driver at this time that has an
output voltage specification such that voltage is pulled to less than 0.8V at low level.
When using the power on reset function built into the hybrid IC, be sure to directly connect Pin 14 to VDD.
We recommend attaching a 1,000pF capacitor to each input to prevent malfunction during high-impedance input. Be
sure to connect the capacitor near the hybrid IC, between Pin 18 (S, G).
When input is fixed low, directly connect to Pin 18. When input is fixed high, directly connect to VDD.
[Current setting Vref]
If the motor current is temporarily reduced, the circuit given below is recommended.
The variable voltage range of Vref input is 0.14 to 1.48V.

[Setting the motor current]
The motor current, IOH, is set using the Pin 19 voltage, Vref, of the hybrid IC. Equations related to IOH and Vref are
given below.
Vref (RO2 ÷ (RO2+RO1))×VDD(5V) ························································· (1)
IOH (Vref ÷ 4.9) ÷ Rs ·················································································· (2)
The value of 4.9 in Equation (2) above represents the Vref voltage as divided by a circuit inside the control IC.
Rs: 0.152Ω (Current detection resistor inside the hybrid IC)
