Operation Descriptions
(1) STB terminal
The operating condition of the IC internal circuit is shown in the following table :
Note) Since the sensor-less block operates, if the motor rotates, it detects the inductive voltage and synthesizes the energization
switching signal which is synchronized with the motor rotation phase.
(2) FR, BR terminal
FR terminal H : Forward rotation
L : Reverse rotation
BR terminal H : Short brake circuit operation
L : Short brake circuit stop
(3) Drive amplifier
The AN3861SA is an IC of current drive type, and the motor drive current Ia is determined by the voltage of OUT1 terminal,
as shown in Fig.1.
The collector voltage value is controlled as shown in Fig.2 since the sink-side output transistor is operated with non-saturation
voltage.
