Status Output - FG and RD Output
The FG output pin is an open collector output which switches ON (pulled low) and OFF (pulled high with an external resistor) depending on the
magnetic phase of the motor. The external pull up resistor should be connected to the FG pin.
The RD output pin is also an open collector which switches ON (pulled low) while the motor rotates and switched off (pulled high with an
external resistor) when the rotor is stopped.
The FG and RD pins have series resistors of
25Ω typical integrated in the FG/RD output structure to increased robustness against reverse
supply connection of the FG an RD pins to ground.
The typical value for external pull-up on FG and RD pins is 10k
Ω.
