BQ27425YZFR-G1 TI Battery Fuel Gauge | 15-DSBGA | I2C, 1-Cell Li-Ion

Product Overview

The BQ27425YZFR-G1 is a single-cell Li-Ion battery fuel gauge IC from Texas Instruments, designed for portable applications requiring accurate battery state-of-charge (SOC) monitoring. It uses the patented Impedance Track™ algorithm to provide real-time battery capacity, voltage, current, and temperature measurements. Housed in a compact 15-DSBGA package, it communicates via I2C interface and supports a wide operating voltage range of 2.45V to 4.5V. The device integrates a 15-bit ADC for current and voltage sensing, and includes an integrated temperature sensor. It is ideal for smartphones, tablets, wearables, and other portable electronics.
