Rf (PWR)
Rf (SNS)
Output current detection. The control block current limiter
operates using the resistor Rf connected between these pins
and ground. Also, the lower side saturation prevention circuit
and the torque ripple correction circuit operate based on the
voltages to this pin. It is especially important to note that,
since the saturation prevention level is set using this voltage,
the lower side saturation prevention circuit will become less
effective in the large current region if the value of Rf is
lowered excessively. Also, the PWR and SENSE pins must
be connected together.

GSENSE
Ground sensing. The influence of the common ground
impedance on Rf can be excluded by connecting this pin to
nearest ground for the Rf resistor side of the motor ground
wiring that includes Rf. (This pin must not be left open.)
33
FR
Forward/reverse selection. The voltage applied to this pin
selects the motor direction (forward or reverse).
(Vth = 2.5 V at VCC = 5 V (typical))
Note: Although the FRAME pins and
the GND pins are not connected
internally, the potentials of the
GND pins and the FRAME pins
externally be identical to assure
ground potential stability.
