Note: For the Hall inputs, the input high state is defined to be the
state where the (+) input is higher than the corresponding
(–) input by 0.01 V or higher, and the input low state is
defined to be the state where the (+) input is lower than
the corresponding (–) input by 0.01 V or higher.
Note: Since this drive technique is a 180° current application
scheme, the phases other than the sink and the source
phases will not turn off.
Pin Functions
Pin No.

GND
Ground for circuits other than the output transistors.
Note that the Rf pin will be at the lowest potential of the output transistors.

FG-OUT
This is the FG amplifier output pin. Internally, it is a resistive load.
4
FR
Forward/reverse switching pin

W-phase Hall output
Used for output current detection. The current limiter circuit operates using the resistor (Rf) connected between
this pin and ground.
Note that the lower side saturation prevention circuit operates according to the voltage that appears on this pin.
Since the over-saturation level is set by this voltage, the response of the lower side saturation prevention circuit
may be degraded in the large current region if the value of Rf is made extremely small.
Note: The "H" state for FR is defined as a voltage of 8 V or
higher, and the "L" state for FR is defined as a voltage of
4 V or lower. (When V
CC
= 12 V.)
