Battery Fuel Gauge IC Protection

Littelfuse offers protection components for battery fuel gauge ICs. Battery Fuel Gauge ICs are critical components to the battery management system within battery-operated electronics, including drones, medical equipment, small appliances, and mobile and wearable devices. Fuel gauge ICs monitor the battery state of charge, sending the data to power management ICs to provide optimal battery life, longevity, and overall system performance. Protecting the fuel gauge ICs is important due to the increased voltage in batteries up to 20V for USB-C. Sustained overvoltage, ESD, overcurrent faults, and overheating are all hazards that could damage the battery management system if proper protection is not used.

Industrial Manufacturing & Processing Portfolio

Littelfuse Industrial Manufacturing and Processing Portfolio encompasses protection, control, and sensing products, including fuses, protection relays, DC disconnect switches, surge protective devices, and temperature sensors. These products safeguard equipment from damage and personnel from injury due to electrical faults, while reducing costs and minimizing downtime. These devices also limit equipment damage and improve productivity.

Surface Mount Thermistors

Littelfuse Surface Mount Thermistors offer a 0.7Ω to 500,000Ω resistance range and a maximum operating range of -55°C to +220°C. The Littelfuse Surface Mount Thermistors portfolio includes surface mount end-banded chip thermistors, leadless top/bottom terminated chip thermistors, inrush current limiters (power thermistors), and more.
