Notes: 1. When the diode Di is used to prevent device destruction from reverse connection, the capacitor Cr must be inserted to assure a path for
regenerative currents. Similarly, if there are no nearby capacitors on the fan power supply line, the capacitor Cr is also required to increase
reliability.
2. The Hall element is biased at a constant voltage of approximately 2.1 V from the HB pin. Thus the LA6538T provides a stable Hall output with
excellent temperature characteristics. The resistor R1 adjusts the Hall output amplitude.
The LA6538T implements linear drive by amplifying the Hall output and applying voltage control to the motor coils. Startup characteristics and
efficiency are improved by using a higher Hall device output. However, the motor can be made to operate more quietly by adjusting the Hall device.
3. If the Hall bias is taken from V
CC
, bias the Hall device at 1/2 V
CC
as shown in the figure.
4. This pin must be left open if unused.
