Lower Nch power FET gate drive output pins.
Upper Nch power FET source voltage detection pins.
Upper Nch power FET gate drive output pin.
Hall input pins. A capacitor is connected for stabilization between these pins and GND.
Reset pin. A resistor is connected between this pin and V5 while a capacitor is connected between this pin and GND.
Reset pin. Connect the resistance between this pin and V5 and the capacitor between this pin and GND.
Pin for changeover of the phase difference of three-phase Hall input (120° and 60°).
HSEL = “L” 120°, HSEL = “H” 60°
Integrating amplifier non-inverted input pin.
Integrating amplifier inverted input pin.
PWM waveform comparison pin (integrating amplifier output pin).
PWM oscillation frequency set pin. Connect a capacitor between this pin and GND.
Hall signal one-shot multi-pulse output.
One-shot multi-pulse width set pin. A resistor is connected between this pin and V5 while a capacitor is connected between this
pin and GND.
Pin to set the operation time of the lock protection circuit. Connect the capacitor between this pin and GND.
Open collector output, with the output being “L” in following cases :
Abnormal Hall input, activation of the low-voltage protection circuit, activation of the lock protection circuit, and activation of the
overheat protection circuit.
Hall signal three-phase composite output pin (open collector output).
Charge pump capacitor output pin. A capacitor is connected between CP1 and CP2.
Low-voltage protective voltage detection pin. A Zener diode is connected in series to set the detection voltage when the supply
voltage of 5V or more is to be detected.
5V power pin (control circuit power supply). A capacitor is connected between this pin and GND.
12V power pin (UL, VL, and WL output power supply). A capacitor is connected between this pin and GND.
Power pin. A capacitor is connected for stabilization between this pin and GND.
Charge pump output pins (UH, VH, and WH output power supply). A capacitor is connected between this pin and V CC .
GND pin.
GND sensing pin, which is connected to the GND side of low-resistance RF connected to the RF pin.
Output current detection pin. Low-resistance RF is connected between RF and GND.
The output current is limited to the value set with I OUT = 0.1/RF. (Current limiting circuit)
These can be used as wiring because they are not connected with the internal parts.
