Status: In Production
The EMC2305 is an SMBus compliant fan controller with up to five independently controlled PWM fan drivers. Each fan driver is controlled by a programmable frequency PWM driver and Fan Speed Control algorithm that operates in either a closed loop fashion or as a directly PWM-controlled device.
The closed loop Fan Speed Control algorithm (FSC) has the capability to detect aging fans and alert the system. It will likewise detect stalled or locked fans and trigger an interrupt.
Additionally, the EMC2305 offers a clock output so that multiple devices may be chained and slaved to the same clock source for optimal performance in large distributed systems.
The ADM00879 Fan Controller Demo Board provides an example of a 12V fan control application using the EMC2305 fan controller and EMC1438 temperature sensor. There are 5 fan channels, 2 on board temperature sensors and 6 remote temperature sensor inputs available.
The demo GUI has options to manually set up all the parameters for the thermal sensor and fan controller, as well as...
