Similarly, Cr is necessary to enhance the reliability when there is no capacitor near the fan power line. To obtain Hall bias from VCC, carry out 1/2×VCC bias as shown in the figure. Linear driving is made through voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the startup performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further. When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 2.0V. Therefore, the Hall element can provide the output satisfactory in temperature characteristics. Adjustment of the Hall output amplitude is made with R1. (When VCC = 12V, the step *2 above proves advantageous for IC heat generation.) Keep this open when not used. When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure.
