STK673-011-E

Continued from preceding page.

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

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

• A Hold terminal which temporarily holds the motor in a state where the phase current is conducted.

• 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 (20kΩ typ)

• 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%

• A built-in current detection resistor (0.227Ω)

• A motor current during revolution can deal with as high as 2.4A at Tc = 105°C and as high as 4A at Tc = 50°C or

lower.
