The I²C lines need pull-up resistors sized for the bus capacitance; the supply decoupling cap should sit within 2 mm of the package edge.","metaTitle":"TI BQ27320YZFR Battery Monitor, I²C, 1-Cell Li-Ion","metaDescription":"Texas Instruments BQ27320YZFR single-cell Li-Ion battery monitor with I²C interface.
