    EMC2105 Single Linear fan controller with 600mA, 5 temperature sensors, higher frequency support, look up table, I2C, alert, thermistor compatible

     

    产品信息

    The EMC2105 is an SMBus compliant fan controller with up to five (up to 4 external and 1 internal) temperature channels. The fan driver can be operated using two methods each with two modes. The methods include an RPM based Fan Speed Control Algorithm and a direct drive setting. The modes include manually programming the desired settings or using the internal programmable temperature look-up table to select the desired setting based on measured temperature.

    The temperature monitors offer 1°C accuracy (for external diodes) with sophisticated features to reduce errors introduced by series resistance and beta variation of substrate thermal diode transistors commonly found in processors.

    The EMC2105 also includes a hardware programmable temperature limit and dedicated system shutdown output for thermal protection of critical circuitry.
