Thermal Management Handbook

By:  Kerry Lacanette

Abstract: Maxim's Thermal Management Handbook includes temperature sensing and fan control concepts, circuits and application guidelines. Thermistors, thermocouples, RTDs, and various IC temperature sensors (local temperature sensors, remote temperature sensors, analog temperature sensors, digital temperature sensors, and temperature switches) are discussed, as well as various approaches to fan speed control.
