BQ79656-Q1
6–16-cell BMS AFE with shunt-current sensing
Adds shunt-current measurement to cell-voltage monitoring and passive balancing, with voltage/current synchronization options. Relative to BQ79616-Q1, the extra acquisition path, filtering and software configuration must enter the SOC error budget.

Key specifications
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.
| OPN | Package | Temperature | Note |
|---|---|---|---|
| BQ79656PAPRQ1 | HTQFP (PAP) · 64 pin | -40 to +125°C (TI OPN listing; verify TA/TJ) | Verify exact OPN, temperature definition and revision; not a stock claim. |

FAQ
What distinguishes it from BQ79616-Q1?
BQ79656-Q1 explicitly supports shunt-current measurement. Compare inputs, timing, registers and calibration; family compatibility is not approval to replace a populated board.
Does the IC alone determine battery SOC?
No. SOC also depends on cell models, temperature, shunt tolerance, calibration and estimation software. The IC supplies measurements, not a pack-level accuracy guarantee.
How should I verify the BQ79656-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.
