It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit.



Features

•Number of motor revolution can be controlled by the frequency of external clock input.

•4 types of modes, i.e., 2, 2-3, W2-3 and 2W2-3-phase excitations, are available whICh can be selected based on rising of clock signals, by switching Highs and Lows of Mode A and Mode B terminals.

•Setting a Mode C terminal Low allows an excitation mode that is based on rising and falling of a clock signal.

By setting the Mode C terminal Low, phases that are set only by Mode A and Mode B can be changed to other phases as follows without changing the number of motor revolution: 2-phase may be switched to 2-3-phase; 2-3-phase may be switched to W2-3-phase; and W2-3-phase may be switched to 2W2-3-phase.

•Phase is maintained even when the excitation mode is changed.

•An MOI output terminal whICh outputs 1 pulse per 1 cycle of phase current.

•A CW/CCW terminal whICh switches the rotational direction.

•An Enable terminal whICh can forcibly turns OFF a MOSFET of a 6 output driving element in normal operation.

•Schmitt inputs with Built-in pull-up resistor (20kΩtyp)

•Motor current can be set by changing the voltage of the Vref terminal (0.63V per 1A, dealing as much as 0 to

1/2VCC2 (4A)).

•The clock input for controlling the number of motor revolution lies in a range of 0 to 50kHz.

•Supply voltage: VCC1 = 16 to 30V, VCC2 = 5.0V ±5%

Stepping Motor Driver (Sine Wave Drive) Output Current: 1.2 A (No Heat Sink*)



Overview

The STK672-060 is a stepping motor driver Hybrid IC that adopts power MOSFETs in its output stage. It features a Built-in mICrostepping controller that implements unipolar constant current PWM drive. Since this IC includes a 4-phase distribution controller for stepping motors, it can

the clock signal.

SANYO -> Panasonic
Description : Unipolar Fixed-Current Chopper (external-Excited PWM) Scheme and Built-in Phase Signal Distribution IC View

Two-Phase Stepping Motor Driver

(Square Wave Drive) Output Current: 1.8 A



Overview

The STK672-330 is a unipolar Fixed-Current Chopper type 2-phase stepping motor driver Hybrid IC. It features power MOSFETs in the output stage and a Built-in phase signal distribution IC. The incorporation of a phase distribution IC allows the STK672-330 to control the speed of the motor based on the frequency of an external input clock signal. It supports two types of excitation for motor control: 2-phase excitation and 1-2 phase excitation. It also provides a function for switching the motor direction.



Features

• The motor speed can be controlled by the frequency of an external clock signal (the CLOCK pin signal).

• The excitation type is switched according to the state (low or high) of the MODE pin. The mode is set to 2-phase or 1-2 phase excitation on the rising edge of the clock signal.

• A motor direction switching pin (the CWB pin) is provided.

• All inputs are Schmitt inputs.

• The motor current can be set by changing the Vref pin voltage. Since a 0.195-Ω current detection resistor is built in, a current of 1 A is set for each 0.195 V of applied voltage.

• The input frequency range for the clock signal used for motor speed control is 0 to 50 kHz.

• Supply voltage ranges: VCC1 = 10 to 42 V, VCC2 =5.0 V ±5%

• This IC supports motor operating currents of up to 1.8 A at Tc = 105°C, and of up to 2.65 A at Tc = 25°C.

• Provides a function that, during clock input, forces all MOSFET devICes to the off state when the ENABLE pin is set low, and then, when ENABLE is set high, resumes operation continuing with the prior excitation timing.



ApplICations

• Two-phase stepping motor drive in send/receive facsimile units

• Paper feed in copiers, industrial robots, and other applICations that require 2-phase stepping motor drive

Part Name(s) : STK672-010 SANYO
SANYO -> Panasonic
Description : Unipolar Fixed-Current Chopper (separate excitation) Type 1.7 A Output Current Stepping Motor Driver with Built-in 4-Phase Distribution Controller View

Overview

The STK672-010 is a 4-phase stepping motor driver IC that adopts power MOSFET for its output stage and that uses a unipolar Fixed-Current Chopper scheme. Since the STK672-010 includes a Built-in 4-phase distribution controller, the stepping motor driver circuit and the control scheme can be simplified, and the stepping motor driver circuit structure can be standardized. The STK672-010 provides high torque, low vibration, and rapid response based on a W1-2 phase excitation drive scheme. The motor current is voluntary set from externals. Since, compared to the earlier STK6770 Series, the STK672-010 has a smaller package size and reduced drive power

dissipation (reduced by 70% over previous products), it provides a wider operating power supply voltage range.
