FGIN-
FGIN+
FG amplifier inputs
An initial reset is applied to the logic circuit block
by connecting a capacitor (of about 0.1
F)
between the FGIN+ pin and ground.
16 to 18
38 to 40
GND
Ground connections
These pins are all connected internally to the
frame.

Hall inputs
High is defined as IN+ > IN-, and low as the
opposite.
An amplitude of 100mVp-p (differential) or more
is desirable in the Hall signals. Connect
capacitors between the IN+ and IN- pins if noise
on the Hall signals causes problems.

RF
Output current detection
Connect a resistor between this pin and ground.
The output limitation maximum current, IOUT, is
set to be 0.52/Rf by this resistor.

This IC implements duty control using output
signal PWM.
These are open collector sink outputs.
