Pin function
• This pin is used for heat dissipation.
Electrically, it must be left open.
10
VCC
11
FG1
• Power for all circuits other than the
output block.
• First speed pulse output. A pull-up
resistor is built in.
12
FG2
• Second speed pulse output. A pull-up
resistor is built in.
13

17
IN2+
Logic high is defined as IN+ > IN–.
18
IN3–
19
IN3+
• Hall element input
Logic high is defined as IN+ > IN–.

Equivalent circuit
21
GND
• Ground for all circuits other than the
output block.
The lowest potential of the output
transistors will be the potential of the Rf
pin.
