Description of Pre-driver Block
*1: <Power supply-GND wiring>
SGND is connected to the control circuit power supply system.
*2: <Power stabilization capacitor>
For the signal-side power stabilization capacitor, the capacitance of more than 0.1
μ
F is used.
Connect the capacitor between VCC and GND with the thick pattern and along the shortest route.
*3: <Power-side power stabilization capacitor>
For the power-side power stabilization capacitor, the capacitance of more than 0.1
μ
F is used.
Connect the capacitor between power-side power supply and GND with the thick pattern and along the shortest
route.
*4: <IN+, IN- pins>
Hall signal input pins
Wiring needs to be short to prevent carrying noise. If noise is carried, insert a capacitor between IN+ and IN-. The
Hall input circuit is a comparator having a hysteresis of 15mV.
It has a
±
30mV (input signal difference voltage) soft switch zone.
It is recommended that the Hall input level is 100mV (p-p) at the minimum.
*5: <CPWM pin>
This is the pin to connect capacitor for generating the PWM basic frequency
Use of CP = 220pF produces oscillation at the frequency of 30kHz which serves as the PWM basic frequency.
Since this pin is also used for the current limiter reset signal, the capacitor must be connected without fail even
when no speed control is implemented.
*6: <CT pin>
This is the pin to connect capacitor for lock detection
Constant-current charging and constant-current discharging circuits are incorporated. When the pin voltage
becomes 3.0V, the safety lock is applied, and when it lowers to 1.0V, the lock protection is reset.
Connect this pin to GND when it is not in use (when lock protection is not required).
*7: <SENSE pin>
This is the pin for current limiter detection
When the pin voltage exceeds 0.21V, current limiting is applied, and the low-side regeneration mode is established.
Connect this pin to GND when it is not in use.
*8: <RD pin>
Lock detection pin
This is the open collector output, which outputs “L” during rotation and “H” at stop. This pin is left open when it is
not in use.
*10: <FG pin>
Speed detection pin.
This is the open collector output, which can detect the rotation speed using the FG output according to the phase
change. This pin is left open when it is not in use.
