, this chip acts as both a precision fuel gauge and a first-line safety supervisor.

The chip is usually "sealed" to prevent unauthorized access. Unsealing requires specific keys, which professional repair software can sometimes bypass or provide. bq40370

The EV2400 or CP2112 are commonly used to connect the battery's SMBus to a PC. , this chip acts as both a precision

Unlike standard commercial chips that utilize TI’s trademarked Impedance Tracking™ math, the BQ40370 relies primarily on the fuel gauging profile. The EV2400 or CP2112 are commonly used to
