Description
Supply pin that provides
Voltage for the source side.
Supply pin that provides Voltage
for the constant Current control
amplifier.
Supply pin that provides Voltage
for all circuit, Except the output
T R, Source side pre-drive, and
Constant current control
amplifier.
Reverse detect pin
• Forward output [H]
• Reverse output [L]
1 Hall wave Schmit comparator
output.
U-phase Hall element input Pin,
and U-phase Schmit
comparator input pin for
Reverse detection.
Logic HIGH is represented by
UIN1>UIN2.
V-phase Hall element input Pin.
and V-phase Schmit comparator
input pin for Reverse detection.
Logic HIGH is represented by
VIN1>VIN2.
W-phase Hall element input Pin.
and W-phase Schmit
comparator input pin for
Reverse detection.
Logic HIGH is represented by
WIN1>WIN2.
This pin provides the lower bias
boltage for the Hall element.
Hone of the circuit operate if the
voltage on this pin is 0.7V or
less, Or if this pin is open.
When driving the motor, the
Voltage on this pin must be 2V
or more.
