Pin function
FG amplifier output pin.
Pin for connecting triangular
wave oscillator capacitor.
Serves for forced startup
waveform generation.
Frequency characteristics pin.
Connecting a capacitor
between this pin and ground
serves to prevent closed-loop
oscillation in the current
control circuitry.
(Lower-side output transistor
drive current)
Frequency characteristics pin.
Connecting a capacitor
between this pin and ground
serves to prevent closed-loop
oscillation in the current
control circuitry.
(Lower-side output transistor
drive current)
Connecting a capacitor
between this pin and ground
activates the coil output
saturation prevention function.
In this condition, the VS pin is
controlled for motor voltage
control.
By adjusting the external
capacitor, torque ripple
compensation can be varied.
