Application Circuit Example (12V)
*1. Power
GND wiring
SGND is connected to the control circuit power supply system.
*2. Power stabilization capacitor
For the power stabilization capacitor on the signal side, use the capacitance of 1μF or more.
Connect VCC and GND with a thick and shortest pattern.
*3. Power stabilization capacitor on the power side
For the power stabilization capacitor on the power side, use the capacitance of 1μF or more.
Connect the power supply on the power side and GND with a thick and shortest pattern.
*4. IN+, IN- pins
Hall signal input pin.
Wiring should be short to prevent carrying of noise.
If noise is carried, insert the capacitor between IN+ and IN- pins.
The Hall input circuit functions as a comparator with hysteresis (15mV).
This also has a soft switch section with
±
30mV (input signal differential voltage).
It is also recommended that the Hall input level is minimum 100mV(p-p).
*5. CPWM pin
Pin to connect the capacitor for generation of the PWM basic frequency
The use of CP = 220pF causes oscillation at f = 30kHz, which is the basic frequency of PWM.
As this is used also for the current limiting canceling signal, be sure to connect the capacitor even when the speed
control is not made.
