Smart thermostats have become a popular method of energy conservation for homes, office buildings, and retail facilities. The market for smart thermostats has been growing at a high CAGR of 22% since 2018. With such high growth, manufacturers can easily justify innovation in new models. Future smart thermostats will provide a wide range of information, including energy usage audits and comparative data on energy consumption before and after an HVAC system upgrade.

The new eFuse Protection ICs Series features protection, sensing, and control features in a single chip. 

The heating, ventilating, and air conditioning (HVAC) market is growing at a 6% compound annual growth rate as annual shipments of AC systems are expected to grow from 110 million units in 2020 to 140 million units in 2024.¹ Large commercial systems will have the highest growth rate resulting from the construction of new healthcare, education, warehouse, government office, and retail facilities.

Designed for industrial applications, including factory automation, Energy Storage Systems (ESS),  and electric vehicle (EV) wall chargers

Littelfuse announced the new EV1K Series Fuses, the first Automotive Grade fuse with a rating of 1000 Vdc. The fuses are designed and tested to meet the overcurrent circuit protection needs of the eMoblilty market, specifically electric vehicle (EV) applications.

Provides exceptional protection for electronics used in appliances, building automation, outdoor lighting, and smart meter applications

Previous articles have discussed several high data rate interfaces such as power-over-ethernet (PoE), USB, HDMI, DisplayPort, and eSATA. This article addresses protection schemes for low-speed interfaces. The discussion will also extend to the power line frequencies and present several protection methods for the AC and DC power supplies.
