Texas Instruments BQ27411-G1 Pack-Side Impedance Track? Fuel Gauge | Battery Gas Gauge BQ27411DRZ-G1A

The BQ27411-G1 is a battery fuel gauging solution designed for single-cell Li-Ion battery packs. It utilizes Texas Instruments' patented Impedance Track,Ñ¢ technology to accurately report remaining battery capacity, state-of-charge, and battery voltage. The device features a compact 12-pin Small Outline No-Lead (SON) package, measuring 2.50 mm x 4.00 mm, making it suitable for space-constrained applications. It requires minimal configuration due to its One Time Programmable (OTP) Non-Volatile Memory (NVM), eliminating the need for an initialization download by the system processor. The BQ27411-G1 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 automatically adjust for battery aging, self-discharge, temperature variations, and rate changes, providing enhanced accuracy in gauging battery health. This device is applicable in various consumer electronics, including smartphones, tablets, and handheld devices.
