Thermal management systems are not simple to design as it has a few major design problems. First, Mission-critical systems cannot tolerate thermal management failures. Either when fans wear out or become blocked or when I2C interfaces to the Host Processor goes down. Such failures can cause a massive chain of additional failures, thereby resulting in substantial damage for the customers. Fans create a substantial amount of noise and also consume significant power at maximum rpm. To combat this, fans must be driven at the minimum feasible rpm and require a controller during thermal algorithms to calculate this rpm. Each thermal management subsystem requires difficult time consuming customization. Each zone of a system will react to temperature differently and will require a different number of fans, different types of temperature sensors, specialized analog ICs for the Sensors, and Microcontroller based firmware algorithms. PSoC solves these problems. PSoC monitors for fan failures and supports redundant I2C interfaces to the Host Processor. The PSoC fan controller component includes thermal algorithms to minimize fan noise and power consumption. One PSoC can control and monitor up to 4 fans and support up to 14 temperature sensors, thereby integrating and customizing the solution including specialized analog ICs for each Temperature Sensor such as the ADC and IDAC ICs. PSoC Temperature Sensor Components provide firmware algorithms for accurate, linearized sensor output conversion and the component configuration tools enable the designer to create customized thermal management configurations in minutes. PSoC will help the designer succeed with a one-chip, customized fail-safe Thermal Management solution.
