Rf
(SENSE)
Rf
(PWR)
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 across this resistor. 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 high 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.)

FR
Forward / reverse selection. The voltage applied to this
pin selects the motor direction (forward or reverse).
(Vth=2.5V at VCC=5V (typical))
23
ADJ
Used for external adjustment of the torque ripple
correction ratio. Apply a voltage externally with a
low-impedance circuit to the ADJ pin to adjust the
correction ratio. The correction ratio falls as the applied
voltage is increased, and increases as the applied voltage
decreases. The torque ripple correction ratio can be
modified by factors in the range 0 to 2 times the ratio that
applies when his pin is left open. (The pin voltage is set to
about VCC / 2 internally, and the input impedance is about
5k
Ω.)
