Manufacturer:TOSHIBA Description:The fan speed is measured by counting the number of the CLK pin period between the rising edges of two fan speed pulses on FG pin. In this way, we are actu- ally measuring the period of the fan speed. To avoid the cost of doing division to obtain the speed, this count number, N, is used in the PWM control algo- rithm, thus, the desired fan speed should be pro- grammed by writing the corresponding count number. The count number is given by: N = (CLK x 30) / (rpm x P) N : Count Number P : FG pulses number per revolution of fan. For CLK = 32768Hz, P = 2 ⇒N = 491520 / rpm For CLK = 16384Hz, P = 2 ⇒N = 245762 / rpm Some selected count numbers are shown below |
