6. Design Problems Engineers Face
Mission-critical systems cannot tolerate Thermal Management failures
When fans wear out or become blocked, or
When SMBus interfaces to the Host Processor go down
Fans create noise and consume significant power at maximum rpm
They must be driven at the minimum feasible rpm to minimize noise and power
They require a microcontroller running Thermal Algorithms to calculate the minimum feasible rpm
Every design requires difficult, time-consuming customization for:
A different numbers of fans and different types of Temperature Sensors
Specialized analog ICs for each Temperature Sensor
Microcontroller-based firmware algorithms to correct and linearize sensor outputs
Storage Rack by IBM
Each Storage Rack has two Thermal Management Systems with 16 fans and two Temperature Sensors
PSoC solves these problems
PSoC monitors the fan rpm for failures and supports redundant SMBus interfaces to the Host Processor
The Thermal Management Kit includes Thermal Algorithms in PSoC User Modules to minimize fan noise and power
One PSoC can control and monitor up to 8 fans and 24 Temperature Sensors
PSoC integrates the specialized analog ICs for each Temperature Sensor, including the ADC and IDAC ICs
PSoC Temperature Sensor User Modules provide firmware algorithms for accurate sensor conversion
