Product details
Overview
BQ7693000DBTR from Texas Instruments is a 6- to 10-series Li-ion/LiFePO₄ battery monitor AFE with integrated cell balancing FETs, low-side charge/discharge FET drivers, and dual thermistor support. It delivers ±15 mV cell voltage accuracy (25°C), 14-bit ADC resolution, and hardware-based OV/UV/OCD/SCD protection for 36-V nominal battery packs used in e-scooters and power tools.
For engineers reviewing the BQ7693000DBTR datasheet, BQ7693000DBTR pinout, BQ7693000DBTR application, or BQ7693000DBTR equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, confirmed alternative parts, and supply-chain-ready availability details - all specific to the BQ7693000DBTR variant.
Technical Context
The BQ7693000DBTR implements a dedicated analog front-end architecture with two independent ADC subsystems: one 14-bit SAR ADC for cell voltage and die temperature (±15 mV accuracy at 25°C), and a separate 16-bit delta-sigma coulomb counter for pack current (±2 LSB INL, 8.44 µV LSB). Its protection logic executes fully in hardware without host intervention, supporting configurable OV/UV trip points (16-LSB step), OCD/SCD thresholds (8–100 mV and 22–200 mV ranges), and programmable delay timers.
It supports random cell connection topology via differential VCn sensing across three voltage domains (VSS, VC5X, VC10X), enabling flexible PCB layout for 6–10S packs. The device operates from 6 V to 36 V supply (BAT–VSS), integrates a 2.5-V LDO (REGOUT), and enters SHIP mode at ≤1.8 µA quiescent current - optimized for long-term storage in industrial battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Cell Count Range | 6 to 10 series Li-ion or LiFePO₄ cells - supports 36-V nominal battery packs with scalable voltage domain partitioning (VSS/VC5X/VC10X). |
| Cell Voltage Accuracy | ±15 mV at 25°C (3.2–4.6 V range) - ensures reliable overvoltage/undervoltage detection within ±0.3% of full-scale. |
| Coulomb Counter Resolution | 8.44 µV LSB - enables precise current integration with ±2 LSB integral nonlinearity for state-of-charge tracking. |
| Protection Response | OCD threshold down to 8 mV (RSNS = 0), SCD response in 35–520 µs - allows fast short-circuit shutdown before MOSFET thermal runaway. |
| Quiescent Current | 130–195 µA in NORMAL mode (ADC + CC active), ≤1.8 µA in SHIP mode - extends shelf life for battery packs in logistics or standby. |
| Thermistor Support | Two independent thermistor inputs (TS1, TS2) with 10-kΩ 103AT bias - enables dual-point temperature monitoring for cell and MOSFET thermal management. |
| I²C Interface | Standard-mode (100 kHz) with optional CRC - simplifies host MCU integration without requiring external protocol translation. |
Pinout & Package
Package: 30-pin TSSOP (DBT), 7.80 mm × 4.40 mm × 1.20 mm body size, lead pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VC0–VC10 | Cell voltage sense inputs | Direct differential measurement of 1st–10th cell voltages across three reference domains (VSS, VC5X, VC10X); enables random cell connection. |
| SRP/SRN | Current sense inputs | Differential input for shunt resistor (–200 to +200 mV range); supports high-accuracy coulomb counting and hardware OCD/SCD detection. |
| CHG/DSG | FET gate drivers | Low-side N-channel drivers with 10–14 V output swing; directly control external charge/discharge MOSFETs without level-shifting. |
| TS1/TS2 | Thermistor bias inputs | Configurable 10-kΩ pull-up for 103AT thermistors; TS1 referenced to VSS, TS2 referenced to VC5X for isolated thermal zones. |
| REGSRC/REGOUT | LDO power path | REGSRC accepts 6–25 V input; REGOUT delivers regulated 2.5 V (±2%) for MCU or peripheral supply - eliminates external regulator. |
| ALERT | Interrupt & override | Open-drain output signals protection events; also accepts override input to manually clear faults or initiate boot sequence. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-based protection engine | Independent OV/UV/OCD/SCD comparators with programmable thresholds and delays - eliminates software dependency for safety-critical shutdown. |
| Integrated cell balancing | Internal 5-mA per-cell balancing FETs - reduces BOM count and PCB area vs. discrete balancing solutions; supports passive top-balancing during charging. |
| Multi-domain voltage sensing | Three independent reference domains (VSS, VC5X, VC10X) - enables arbitrary cell interconnection order and simplifies routing in high-cell-count packs. |
| Ultra-low-power SHIP mode | ≤1.8 µA total supply current - preserves battery capacity during shipping, storage, or long-term idle periods without external wake-up circuitry. |
| No EEPROM programming required | Factory-configured I²C address (0x08), LDO voltage (2.5 V), and CRC option - reduces manufacturing test complexity and eliminates field reconfiguration risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery monitor AFE applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ7694000DBTR | Supports 9–15S cells, 44-pin TSSOP, higher voltage tolerance (up to 48 V nominal), adds third thermistor (TS3) and extended cell sensing (VC11–VC15). | Required for ≥48-V systems (e.g., e-bikes, ESS); not pin-compatible due to larger package and additional pins. | Select when scaling beyond 10S or needing triple-thermistor redundancy - requires PCB redesign. |

FAQ
What is the maximum number of series cells supported by the BQ7693000DBTR?
The BQ7693000DBTR supports up to 10 series-connected cells in Li-ion or LiFePO₄ configurations. This is fixed by its internal voltage domain architecture (VSS, VC5X, VC10X) and pinout - it cannot monitor 11 or more cells. Applications requiring >10S must use BQ7694000DBTR or daisy-chained architectures.
Does the BQ7693000DBTR require external EEPROM or firmware programming for basic operation?
No. The BQ7693000DBTR ships with factory-programmed settings including I²C address (0x08), LDO output voltage (2.5 V), and CRC enable/disable state. No EEPROM programming, calibration, or firmware initialization is needed to achieve full cell monitoring, protection, and balancing functionality.
What is the purpose of the VC5X and VC10X pins on the BQ7693000DBTR?
VC5X and VC10X serve as intermediate voltage references that partition the 10-cell stack into three domains: VSS–VC5X (cells 1–5), VC5X–VC10X (cells 6–10), and VC10X–BAT. This enables differential sensing across each domain and supports random physical cell connection order - eliminating strict serial routing constraints on the PCB.
Can the BQ7693000DBTR drive high-side N-channel FETs directly?
No. The BQ7693000DBTR provides only low-side N-channel FET drivers (CHG and DSG pins). Driving high-side N-FETs requires an external charge pump or level shifter. The datasheet explicitly states "High-Side FET Driving" as an added feature in Revision H - but only for the BQ76940, not the BQ7693000DBTR.
What is the minimum operating temperature range for the BQ7693000DBTR?
The BQ7693000DBTR is specified for continuous operation from –40°C to +85°C ambient temperature. Its die temperature sensor (VDIETEMP) and cell voltage ADC maintain accuracy across this full range, with cell voltage error bounded at ±50 mV (–40°C to +85°C, 2.0–5.0 V range), enabling deployment in outdoor power tools and cold-climate e-scooters.
