Fan managers
14 August 2002, Power Electronics / Power Management
Microchip's TC654, TC655, TC664 and TC665 fan speed controllers monitor r.p.m. data and can detect when a fan wears out, allowing users to replace fans before they malfunction. Integrating 'FanSense' technology, the devices support fans operating at 5-, 12-, 24- and 48 V and rated up to 1 A, by using an external power device. 'FanSense' is a method of sensing when a fan pulse is present, allowing detection of fan-fault conditions and protection against fan failure. In addition to extending fan life, the ability to adjust speed according to temperature also reduces acoustic noise. Fan speed can be programmed either by the output of a remote thermistor or through the SMBus interface. The TC654/5 are able to monitor two fans simultaneously, whereas the TC664/5 are for single-fan applications. The TC655 and TC665 devices also assert an over-temperature signal to identify over-heating conditions. In 10-pin MSOP, the devices operate over 3,0 to 5,5 V and -40 to +85°C.
