LED Lighting Solutions

Littelfuse LED Lighting Solutions support all facets of the LED lighting market with innovative solutions that not only meet regulatory standards but also increase equipment safety and reliability. To help protect end-users, Littelfuse works closely with many LED driver IC suppliers, to ensure their evaluation boards and reference designs comply with safety and surge immunity requirements. They also assist LED lighting power supply manufacturers in designing optimal protection schemes for their driver modules. At the OEM level, they cooperate with luminaire and lamp manufacturers to ensure their products are optimally designed for robust surge immunity protection.

Electrical Vehicle AC Chargers

Littelfuse provides a wide range of products that are suitable for Electric Vehicle AC Chargers. Although simpler in nature compared to DC chargers, AC charging stations safely deliver AC power from the electrical grid into the vehicle. Due to space and weight constraints in the vehicle, on-board chargers and AC charging stations are typically limited to lower amounts of power (22kW or less), which means charging time is slow – taking several hours. These systems also rely on a vehicle’s on-board charger to enable the conversion of AC power from the grid into DC power to charge the vehicle’s battery. It’s critical that proper measures are taken to safeguard both the charger and vehicle.

Transient Voltage Suppressor (TVS) Diodes

Littelfuse TVS (Transient Voltage Suppression) Diodes are a broad range of circuit protection products designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). Lightning strikes, inductive load switching, and ESD cause electrical over-stresses associated with the transmission on data lines and electronic circuits. Offered in a variety of surface mount and through-hole circuit board mounting formats, the TVS Diode portfolio includes high peak pulse current and peak pulse power options up to 20kA and 30kW, respectively. Littelfuse TVS Diodes are chosen for the fast response time (low clamping voltage), lower capacitance, and low leakage current. TVS Diodes are available in both unidirectional (unipolar) or bidirectional (bipolar) diodes circuit configurations. 

Solutions de thermostats intelligents

Les composants des solutions de thermostats intelligents de Littelfusepermettent aux concepteurs de mettre en œuvre des solutions d'Internet des objets (IoT) pour renforcer l’efficacité énergétique et surveiller la consommation d'énergie. Les solutions de thermostats intelligents de Littelfuse complètent d'autres caractéristiques de bâtiment intelligent, y compris les systèmes de sécurité et de sécurité.

Littelfuse High Reliability TVS Diodes

Diodes TVS CMS uni/bidirectionnelles SMF

Les diodes TVS CMS uni/bidirectionnelles de Littelfuse sont conçues pour protéger les équipements électroniques sensibles des tensions transitoires induites par la foudre et d'autres événements de tension transitoire. Le boîtier SMF (SOD-123FL) offre une empreinte 50 % plus petite que le boîtier SMA et offre une faible hauteur de 1,1 mm. Les composants SMF sont idéaux pour la protection des interfaces E/S, du bus V_CC et d'autres circuits vulnérables utilisés dans les téléphones portables, les dispositifs portables, les machines professionnelles, les alimentations électriques et d'autres applications grand public.

Electrical Vehicle DC Fast Chargers

DC charging stations are designed to convert the electrical grid’s AC power into DC power that can then be fed directly into a vehicle’s battery system for fast charging – in 30 minutes or less. Because the conversion from AC to DC power is being done in the charging station, these units can provide higher levels of power (50kW to 350kW and beyond) to the vehicle compared to AC charging stations. Working with tens to hundreds of kilowatts of power, efficient conversion, reliability of the system, and user safety are critical.

Battery Management System Solutions

Littelfuse Battery Management System Solutions provides components that protect against overcurrents, surges, and Electrostatic Discharge (ESD) that threaten the safe operation of Battery Management Systems (BMS) in industrial tools and robotics, as well as e-mobility, mobile, and wearable applications.
