Introduction

Temperature control traditionally uses min or max temperature thresholds to take corrective action using the system's thermal cooling system or shut-down devices. This process does not address over temperature conditions that occur between temperature conversion samples, or allow systems to predict thermal issues before they occur. Additionally, as system designs become more compact and higher power, thermal limit excursions can occur quicker leading to system damage.
