Texas Instruments BQ27411-G1 Pack-Side Impedance Track? Fuel Gauge | Battery Gas Gauge BQ27411DRZR-G1C

The BQ27411-G1C from Texas Instruments is a battery fuel gauging solution designed for single-cell Li-Ion battery packs. It utilizes the Impedance Track,Ñ¢ algorithm to accurately report remaining battery capacity, state-of-charge, and battery voltage. The device features a compact 12-pin SON package measuring 2.50 mm x 4.00 mm, making it suitable for space-constrained applications. It requires minimal configuration and employs One Time Programmable (OTP) Non-Volatile Memory (NVM) to eliminate the need for initialization downloads by the system processor. The BQ27411-G1C operates with a 400-kHz I¬=C serial interface and includes an integrated low-dropout (LDO) regulator, allowing it to be powered directly from the battery. Additionally, it incorporates an internal temperature sensor and can adjust for battery aging, self-discharge, temperature variations, and rate changes, providing reliable battery state-of-health estimation. This product is ideal for applications such as smartphones, tablets, digital cameras, and handheld terminals.
