As rechargeable battery technology increases battery charge density and capacity, more and more products are operating on Lithium-ion (Li-ion) battery power.

Littelfuse, Inc. announced an update to its C&K Switches KSC2 Sealed Tactile Switch product line with Precise Electrical Height. The KSC2 series is ideal for surface-mount technology (SMT) and is IP67-rated with 3.5 mm high momentary-action tactile switch featuring a soft actuator.

Chicago, Illinois. Littelfuse, Inc. introduced its LS0502SCD33S, the newest member of the eFuse Protection IC lineup. The design introduces the Single Cell Super Capacitor Protection IC, developed specifically for charging backup power sources under harsh environments. The LS0502SCD33S leverages supercapacitor technology delivering a broad temperature range and offers superior power/energy density. It efficiently manages high operational voltages (above 3 V).

New technology is showing up everywhere, including in the elevators and escalators that all of us use to reach the floors of commercial buildings, shopping malls, apartment complexes, and condominiums. Nearly 20 million elevators and escalators are operating worldwide, and the number of installations is growing substantially. In 2021, new installations exceeded a quantity of one million units. Market drivers include the growth in cities' population, which requires more apartment buildings and office buildings. Other drivers include adding intelligent sensing and wireless connectivity to reduce unplanned downtime and increase user convenience.

Company's new resistor family is designed to provide overcurrent protection, current monitoring, and control of critical electronics.

The rapid development of smart homes and advanced building automation is enabled by a combination of smartphone, networking, and internet-of-things (IoT) technologies. These technologies provide increased security, automation, and control that gives homeowners and office occupants enhanced convenience, comfort, and greater safety. Wherever a homeowner or office occupant is, they can easily view the status of their door locks and window and door access.

This article provides designers with information on three critical technologies: protection, control, and sensing, for developing an electric water heater robust to external overloads, transients, and ESD. The components representing these technologies will help create a safe, efficient, long-life water heater that safely controls water temperature. By using the recommended components, design engineers will achieve the goal of developing high-quality, reliable, smart water heaters.
