It communicates over an I²C bus, making it straightforward to integrate with a host MCU in a portable or standby-power system. The 14-TSSOP package keeps the footprint small for space-constrained battery packs. ## Industrial temperature range and package fit Rated for -40°C to 85°C ambient, this monitor suits outdoor telecom cabinets, industrial UPS battery trays, and electric-vehicle auxiliary packs that see temperature swings. The 14-TSSOP body (4.40 mm width) is a common footprint; verify land pattern against your existing 14-pin TSSOP layout. ## Sourcing and lifecycle The BQ34110PW carries an Active product status with ROHS3 compliance.","metaTitle":"TI BQ34110PW Battery Monitor, I²C, 1-4 Cells, 14-TSSOP","metaDescription":"Texas Instruments BQ34110PW multi-chemistry battery monitor for 1-4 cells.
