Battery Fuel Gauge ICs:

52 Products Found

Newark offers an exclusive range of fuel gauge ICs from leading manufacturers. These can be in the battery pack or the handheld device and integrate functions to monitor the battery voltage, current and temperature. They are used in portable devices, electric vehicles (EVs), industrial equipment, and IoT applications.

Battery Fuel Gauge ICs combine a small footprint with excellent measurement accuracy and extremely low power consumption to increase battery runtime and lifespan in mobile phones, multimedia players, digital cameras, and other space-constrained portable gadgets. They are essential for accurately measuring and reporting the state of charge (SoC) and state of health (SoH) of batteries in modern electronics. 

They can be placed in battery packs or handheld devices and integrate functions to monitor battery voltage, current, temperature, and other parameters. These specialized power management ICs ensure efficient battery utilization by providing precise data on remaining capacity, voltage, current, and temperature. 

Fuel gauge ICs improve battery life and safety by predicting battery behavior, preventing overcharging, and enabling smart power management. Selecting the right battery fuel gauge IC is vital for optimizing device performance and reducing operational risks. Whether for single-cell lithium-ion batteries or multi-cell configurations, these ICs support various chemistries and communication protocols such as I2C and SMBus.
