Pin Assignment
Pin No.
Pin
Function
Equivalent circuit
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
).
CTLREF
12
CTL
Speed control input. The control implemented is fixed current
drive controlled by current feedback from Rf.
Gm = 0.58/V (typical) when Rf = 0.5
11
LIM
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
.
13
V
CC
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.
