Output block power supply and current
detection.
Insert the resistor Rf between this pin and
The output current will be limited to the current
value
IOUT = VRF/Rf.

IN1+
IN1-
IN2+
IN2-
IN3+
IN3-
Hall element inputs.
The high state is when IN+ is greater than IN-,
and the low state is the reverse.
An amplitude of at least 100mVp-p (differential)
is desirable for the Hall element signal inputs. If
noise on the Hall signals is a problem, insert
capacitors between the IN+ and IN- inputs.
13
14
FGIN+
FGIN-
FG input.
If noise on the FG signal input is a problem,
connect a filter consisting of either a capacitor
or a capacitor and a resistor.
15
GND1
Control circuit block ground
16
GND2
SUBGND pin
17
PWM
Sets the PWM oscillator frequency.
Insert a capacitor between this pin and ground.
The PWM oscillator frequency is set to about
34kHz when a 680pF capacitor is used.
