    EMC2113 Single PWM fan controller with closed loop, speed table, high frequency support, 4 temperature sensors, I2C, block read, alert

     

    产品信息

    The EMC2113 is an SMBus compliant fan controller. 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 PWM 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 EMC2113 includes a temperature monitor that measures up to three (3) external diodes and the internal diode. 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 device includes high and low limits for all temperature channels as well as a hardware set critical temperature limit. This hardware set limit drives a dedicated system shutdown pin.

    Finally, the device includes an open-drain, active low interrupt pin to flag temperature or fan control errors.
