Product details

What the 6–10 cell range means for your pack design

The BQ7693003DBTR is a battery monitor IC from Texas Instruments that handles 6 to 10 series cells, covering the sweet spot for mid-size lithium-ion, LiFePO4, and lead-acid battery packs used in power tools, e-bikes, UPS systems, and energy storage. The I²C interface lets a host MCU read individual cell voltages, check for fault conditions, and manage charge/discharge FETs without a dedicated SPI bus or extra GPIOs. The monitor checks these thresholds autonomously and can drive an alert to the host or directly control protection FETs.

Package and temperature: where it fits on the board

Housed in a 30-TFSOP (4.40 mm wide, 0.173" pitch) — the same footprint as a standard 30-TSSOP — the BQ7693003DBTR is a surface-mount part suited for compact, mixed-signal boards. ROHS3 compliance avoids any RoHS exemption sunset risk.

Frequently asked questions

Does BQ7693003DBTR support 10 cells?

Yes, it supports 6 to 10 series cells. That range covers most common mid-voltage lithium and lead-acid packs.

What are alternatives to BQ7693003DBTR?

The BQ79612PAPRQ1 is an automotive-grade (AEC-Q100) monitor for single-cell Li-ion with SPI/UART and over-temperature protection, but it does not cover the 6-10 cell range. The BQ2084DBT-V143 handles 2-4 cells via SMBus and targets Li-ion/polymer packs — a different cell-count tier. Neither is a direct pin-compatible drop-in; the BQ7693003DBTR occupies its own niche for 6-10 cell packs with I²C.
