STK673-010-E Datasheet, PDF (2/15 Pages) Sanyo Semicon Device – 3-Phase Stepping Motor Driver Output Current 2.4A

STK673-010-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.
