CTL
Speed control input. The control implemented is fixed
current drive controlled by current feedback from Rf.
Gm=0.58 / V (typical) when Rf=0.5W
12
CTLREF
Control reference voltage. While this pin is set to about
0.43
×VCC internally, this voltage can be modified by
applying a voltage from a low-impedance circuit.
(The input impedance is about 4.3k
).
13
LIM
Current limiter function control. The output current can be
varied linearly by applying a voltage to this pin.
The slope is 0.5A / V (typical) when Rf=0.5
.

VCC
Power supply for all internal blocks other than the output
block. This voltage must be stabilized so that noise and
ripple do not enter the IC.

Control Function and Current Limiter Function
Note: In the FR column, “H” refers to a voltage of
2.75V or higher, and “L” refers to 2.25V or
lower (when VCC=5V.)
Note: In the Hall input column, “H” refers to the state
in the corresponding phase where the +input is
at a potential at least 0.01V higher than the
-input, and “L” refers to the state where the
-input is at a potential at least 0.01V higher than
the +input.
