fan tach circuit
,An open collector design, typically used for CPU fan tach signals, is a very simple digital way to transfer rpm information. As you can see in the circuit diagram, the internal transistor sinks current to ground when it is conducting. The transistor condu,Why and How to Control Fan Speed for Cooling Electronic Equipment. by Mary Burke. Introduction. Interest has been growing in integrated circuits for controlling the speed of cooling fans in personal computers and other electronic equipment. Compact electr,Tachometer outputs (speed sensors) can address these issues. Figure 11 shows a circuit that uses a fan with a tachometer. The MAX6625 measures the temperature and reports it to the microcontroller via an I²C-compatible 2-wire interface.
