Battery Monitoring Fuel Gauge IC manufacturers | Maxim, ST, ON semi

This page covers Battery Monitoring Fuel Gauge IC manufacturers or vendors. The manufacturers of Fuel Gauge IC used for battery monitoring include Maxim Integrated, STMicroelectronics, ON Semiconductor etc.

Introduction: The fuel gauge IC is used to monitor state of charge and health of the battery. This IC helps in predicting how long battery can provide the power under specific operating conditions. This helps user to avoid sudden shutdown of the battery operated device in order to enhance user experience.

Fuel Gauge IC ?

As mentioned this IC is used to monitor battery voltage continuously. The applications of fuel gauge IC include wireless speakers, medical devices, mobile phones, tablets, laptops, PCs, e-bikes, financial terminals, printers, cameras, robots, AR/VR devices etc.

All the ICs will be interfaced with the battery terminals. The IC stores various parameters in internal registers. All these ICs have I2C interface which provides access to registers with vital informations such as remaining capacity of battery, state of charge (SOC) , temperature etc. I2C interface has two pins viz. serial clock and serial data.
