Programmable PWM output and\r\ntachometer input, with internal and external temperature sensing capabilities,\r\nwith an accuracy of 1° C, making it the perfect friend for any 3 or 4-pin PC\r\nfan you may find. The four pin PC fan has a power and ground pin (red and\r\nblack), followed by two more pins. Other of these additional pins, the PWM\r\npin, allows you to set the speed of the fan. The last TACH pin is used for\r\ntachometer output, allowing EMC2101 to monitor the speed of the fan to ensure\r\nit operates as expected. This chip will handle all your affairs through daily\r\nI2C instead of using PWM outputs and counter inputs on the microcontroller. In\r\naddition to allowing you to control the fan, EMC2101 also includes a\r\nconnection for an internal temperature sensor and an external temperature\r\nsensing diode. This simple small chip can be easily used to help provide\r\ncooling or ventilation for your next project. You can even use it to help\r\nquiet existing projects or crack noisy electronic devices with high fan noise.\r\nBy allowing you to run the fan at a slower speed when cooling demand is\r\nmoderate, EMC2101 can help reduce the vibration noise generated when the fan\r\nis running at full speed.2.Feature: 1\u0026gt;.Low-power design 2\u0026gt;.Ultra small volume\r\n3\u0026gt;.Simple and easy to operate3.Parameter: 1\u0026gt;.Work Voltage: DC 3.3V-5V 2\u0026gt;.Size:\r\n2618mm4.Package: 1\u0026gt;.1pcs EMC2101 I2C PC Fan Speed Controller\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n \u003cul class=\"a\"\u003e\r\n \u003cli\u003eEMC2101 is a fan controller with temperature monitoring function that will handle all of this for you.
