AGC
A capacitor is inserted between this pin and
ground. The AGC circuit controls the Hall bias
current so that the coil output slope remains
fixed.

ST, BY
VCC2 max
All circuits stop when this pin falls below 0.4V or
is open. In this state, the circuit current will be
10
μA or lower. Set this pin to 2V or higher to
operate the LB1882V in the motor drive state.
15
FRC
VCC2 max
Motor forward/reverse switching.
Low level: Forward (0 to 0.4V)
High level: Reverse (1.6V to VCC2)
