... 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 2.1V from the HB pin. Thus the LA6538T provides a stable Hall output with excellent temperature characteristics. The resistor R1 adjusts the Hall output amplitude ...
