BQ79612-Q1

6–12-cell monitor and balancer

A stackable monitor for 12-cell modules, combining cell-voltage measurement, temperature diagnostics and internal passive balancing. Against the 16-cell option, first map actual cell connections and unused channels; a shared family does not eliminate a design review.

LifecycleActive

In one sentence: Qualification is grounded in this TI product's documentation; no grade is inferred from temperature. An ordering table may show junction or variant-specific limits, which must be distinguished from ambient conditions. TI explicitly lists Functional Safety-Compliant. This is a device-documentation category, not system ASIL certification; assess the exact function, assumptions and safety manual.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

Why select 12 rather than 16 channels?

Select by module cell count, input wiring, unused-channel rules and platform reuse. BQ79612-Q1 supports 6–12 cells; more channels do not automatically improve accuracy or reduce validation.

Does 240mA mean all cells can balance continuously?

No. Balance resistors, adjacent-channel restrictions, junction temperature and thermal management constrain continuous current and duty cycle. Validate the datasheet conditions and module thermal design.

How should I verify the BQ79612-Q1 orderable?

The page lists 1 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
