This chip is frequently found in high-end Dell battery models, such as: Dell Latitude 7285 keyboard batteries. Dell PW23Y batteries. Compatible with standard communication protocols used in smart battery systems. NLBA1 Laptop Battery Analyzer and Repair Tool TI E2E support forums
Note: Values below are illustrative; always consult the exact bq40370 device datasheet for guaranteed numbers and conditions.
Unlike standard commercial-off-the-shelf fuel gauges, the BQ40370 relies on a hybrid micro-architecture that bridges legacy techniques with advanced algorithmic computation.
: It acts as the "brain" of the battery management system (BMS), tracking voltage, current, and temperature to ensure safe and efficient operation. Hardware Compatibility : Technicians often use the EV2400 programmer NLBA (Laptop Battery Analyzer)
If your laptop uses a battery with this chip and you are experiencing power issues, you can check its status using these built-in tools:
A: It is technically possible to purchase the IC, but without official datasheets, development tools, or support from TI, it would be exceptionally challenging to integrate it into a new design. It is not recommended for hobbyist or new commercial projects.
⚠️ Incorrect CEDV parameters will cause SOC jump errors. Always validate with a full discharge test.
