It reports state-of-charge, voltage, and temperature over an HDQ or I²C bus to a host controller. The -40°C to 85°C operating range and surface-mount 14-TSSOP package make it a natural fit for industrial backup-power systems, UPS battery packs, telecom rectifiers, and outdoor solar-storage monitors where the battery chemistry is fixed to lead-acid. ## Lifecycle and supply posture The BQ34Z110PWR is listed as Active with ROHS3 compliance.","metaTitle":"TI BQ34Z110PWR Impedance Track™ Lead-Acid Battery Monitor","metaDescription":"TI BQ34Z110PWR fuel gauge for lead-acid batteries.
