Function

Ground for circuits other than the output transistors.

Note that the Rf pin will be at the lowest potential of the output transistors.

This is the FG amplifier output pin. Internally, it is a resistive load. (Pull up)

Forward/reverse switching pin

Corrects the frequency characteristics of the saturation prevention circuit loop and current limiter circuit.

U-phase Hall input. Logic high refers to the state where IN+ > IN-.

V-phase Hall input. Logic high refers to the state where IN+ > IN-.

W-phase Hall input. Logic high refers to the state where IN+ > IN-.

Power supply provided to all IC internal circuits other than the output block.

This voltage must be stabilized so that ripple and noise do not enter the IC.

Output block power supply

Used for output current detection. The current limiter circuit operates using the resistor (Rf) connected between this

pin and ground.

Note that the lower side saturation prevention circuit operates according to the voltage that appears on this pin.

Since the over-saturation level is set by this voltage, the level of the lower side saturation prevention circuit may be

degraded in the large current region if the value of Rf is made extremely small.

U-phase Hall output.

V-phase Hall output. (These pins include internal spark killer diodes.)

W-phase Hall output.
