It monitors one series cell (1S) and reports state-of-charge, voltage, current, and temperature over the two-wire bus. ## What the AEC-Q100 rating means for the BOM This means the IC has passed the full reliability stress battery — temperature cycling, ESD, latch-up, and extended life tests — required for tier-1 automotive supply. ROHS3 compliance is confirmed, so the part clears EU RoHS and similar restricted-substance regulations without an exemption. The 14-pin TSSOP is a common form factor for analog mixed-signal ICs; the 0.65 mm pitch routes comfortably on a two-layer board with 0.25 mm traces.","metaTitle":"BQ34210IPWRQ1 Texas Instruments Battery Power Management","metaDescription":"Texas Instruments BQ34210IPWRQ1 single-cell multi-chemistry battery power management IC.

It is a battery protection IC (over-voltage monitor for 2-4 series Li-ion cells), not a fuel gauge or power management IC. The BQ296217DSGT monitors fault conditions and triggers protection FETs; the BQ34210IPWRQ1 measures coulomb count, voltage, and temperature to report state-of-charge over I²C. They serve different functions in the battery management system."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ34210IPWRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ34210IPWRQ1 when reusing this data.
