The MAX31782 from Maxim Integrated Products, Sunnyvale, CA, is a system management microcontroller that combines 6 temperature measurement channels with 6 channels of closed-loop fan control. The C-language programmable device lets system designers implement zoned-cooling schemes to minimize system power consumption and increase reliability through reduced fan wear. The microcontroller, based on a 16-bit MAXQ RISC microcontroller core with 32 Kword flash and 1 Kword RAM, incorporates a 6-channel, 12-bit ADC with a temperature sensing analog front end that allows direct connection to thermal diodes. Resolution is 0.125°C.
