Communicates with the host device (laptop) via SMBus, transmitting data like cycle count, cell voltage, temperature, and full charge capacity (FCC).
It is designed for battery packs, commonly used in:
: It uses an ACEDV (Adaptive Compensated End-of-Discharge Voltage) algorithm, which is a hybrid of the standard CEDV and Impedance Track (IT) methods. bq40370
A: The BQ40370 has a unique Device ID (9DB2) compared to the BQ4050 (9E34). The BQ40370 is a custom chip, likely with proprietary firmware tailored for specific OEMs, while the BQ4050 is a publicly available device with full support from Texas Instruments.
systems like the WDX0R and 3DDDG—it serves as the "brain" of the battery pack, managing safety, charging profiles, and capacity estimation. NLBA1 Laptop Battery Analyzer and Repair Tool Technical Architecture and Gauging Method Communicates with the host device (laptop) via SMBus,

The following table summarizes common issues reported by users and repair technicians working with BQ40370-based batteries: The BQ40370 is a custom chip, likely with
If one cell group drops significantly lower than the others.
Unlike standard commercial-off-the-shelf fuel gauges, the BQ40370 relies on a hybrid micro-architecture that bridges legacy techniques with advanced algorithmic computation.
