NAME
NUMBER
ENABLEn
22
I
Enables and disables the motor – active
low. Internal pulldown resistor.
FAULTn
17
OD
Fault indicator – active low when
overcurrent, overtemperature, or rotor stall
detected. Open-drain output.
HALLOUT
16
OD
Outputs a TACH signal generated from the
Hall U sensor. Open-drain output.
LOCKn
18
OD
This open-drain output drives low when a
spinning motor reaches a consistent speed,
based on the period of Hall U.
