Control Characteristics
Control Limiter Characteristics
Slope: 0.50 A/V (typical)
I OUT
Pin No.
Pin
Function
Equivalent circuit
Input used when the FG amplifier is used as an inverting
input. A feedback resistor must be connected between FGOUT
and this pin.
3
FGIN+
Noninverting input used when the FG amplifier is used as a
differential input amplifier. No bias is applied internally.
4
FGIN–
FG amplifier output. There is an internal resistive load.
5
FGOUT
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 4.3 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
.
8
LIM
U phase Hall element inputs.
Logic high is defined as states where IN+ > IN–.
10
11
UIN+
UIN–
V phase Hall element inputs.
Logic high is defined as states where IN+ > IN–.
12
13
VIN+
VIN–
W phase Hall element inputs.
Logic high is defined as states where IN+ > IN–.
14
15
WIN+
WIN–
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.
16
VCC
