Function
Equivalent circuit
Input used when the FG amplifier is used as an inverting
input. A feedback resistor must be connected between FG
OUT
and this pin.
3
FG
IN
+
Noninverting input used when the FG amplifier is used as a
differential input amplifier. No bias is applied internally.
4
FG
IN
–
FG amplifier output. There is an internal resistive load.
5
FG
OUT
Control reference voltage. While this pin is set to about
0.43
×
V
CC
internally, this voltage can be modified by
applying a voltage from a low-impedance circuit.
(The input impedance is about 4.3 k
).
6
FGS
Speed control loop frequency characteristics correction.
9
FC
Speed control input. The control implemented is fixed current
drive controlled by current feedback from Rf.
Gm = 0.58/V (typical) when Rf = 0.5
.
7
CTL
Current limiter function control. The output current can be
varied linearly by applying a voltage to this pin.
The slope is 0.5 A/V (typical) when Rf = 0.5
.

LIM
U phase Hall element inputs.
Logic high is defined as states where IN+> IN–.
