Description
16
FGOUT_D
FG amplifier output.
8
OSC
Pin for connecting triangular wave oscillator
capacitor.
Serves for forced startup waveform
generation.
9
FC1
Frequency characteristics.
Connecting a capacitor between this pin
and ground serves to prevent closed-loop
oscillation in the current control circuitry.
4
FILTER
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.
11
PGOUT_D
PG amplifier output.
12
PGC
PG amplifier peak hold capacitor
connection.
