Description
Equivalent Circuit
3
VCC2
4V
to
13.6V
Power supply that provides the source side
predriver voltage.
4
VCC3
4V
to
13.6V
Power supply that provides the constant
current control amplifier voltage.
8
VCC1
4V to 6V
Power supply that provides all voltages other
than those for the output transistors, the source
side predrivers, and the low-current control
amplifier.
16
RS
Reverse rotation detection
Outputs a high level for forward rotation.
Outputs a low level for reverse rotation.
17
FG
One or three Hall sensor Schmitt trigger
comparator synthesized output
10
UIN1
9
UIN2
U phase Hall sensor input and reverse rotation
detection U phase Schmitt trigger comparator
input.
The logical high state indicates the state where
UIN1 > UIN2.
12
VIN1
11
VIN2
V phase Hall sensor input and reverse rotation
detection V phase Schmitt trigger comparator
input.
The logical high state indicates the state where
VIN1 > VIN2.
14
WIN1
13
WIN2
1.2V
to
VCC1-1V
W phase Hall sensor input and reverse rotation
detection W phase Schmitt trigger comparator
input.
The logical high state indicates the state where
WIN1 > WIN2.
15
VH
Provides the Hall sensor low side device
voltage
.
19
S/S
0V
to
VCC1
All internal circuits are stopped by setting this
pin to 0.7V or lower or by setting it open.
Set this pin to 2.0V or higher when driving the
motor.
21
SIG GND
Ground for all systems except the output
system.
