Thermal Management ICs are a semiconductor device that controls the power in a circuit based on temperature. The function of these ICs are Fan Control, Hardware Monitor, Temp Monitoring System, Thermal Monitor, Thermocouple Amplifier, Thermocouple Conditioner, and a Thermometer – Thermostat. The sensing temperature is from -260°C to +1800°C with an output type of I2C, SMBus, Active low/Active High, Analog Voltage, Open Drain, PWM, SPI, 2-Wire Serial, and Parallel – Serial.
