Application Informations
1. A Diagram Summarizing The Entire System
Figure 1.
Figure 1 is a conceptual diagram of the FAN8486D. It turns on or off depending on the signal of the hall sensor used for sens-
ing the rotor position of motor.
The AMP, G
M
(Feedback) and output blocks are circuits used to determine current gain of FAN8486D.
Furthermore, HallIN represents the hall signal switch.
It supplies stable bias to each V
REG
block. The TSD block is a thermal shutdown circuit that protects the IC during an high
temperature inside the IC.
Moreover, FG. and PG. blocks output individual signals generated in the motor using the amplifier and comparator.
These signals transmit motor speed and position data to controller of external servo etc. for their control.
2. Current Control
Figure 2 simplifies figure 1.
The supplied I
O
current drives the motor and the Ic current controls the motor speed.
