10. Design Checklist for bq40370

I assume you want the proper (technical) features/specifications for the BQ40370 battery-monitoring IC. Here are the key features and specs (concise): bq40370

• Monitor FAULT/STATUS as interrupt-driven signals to quickly respond to protection events.
• Implement logging of fault events with timestamps for field diagnostics.
• On restart after fault, implement safe re-enablement sequence: check voltages, verify temperature, attempt controlled soft-start.
• Provide user-visible indicators (LEDs or UI messages) for charge, discharge, and fault states.

Fault Reporting

Capacity Jumps:

A common symptom of a failing BQ40370-based battery is a sudden drop in charge percentage (e.g., jumping from 30% to 5%). This usually indicates an "OverEstimated FCC" or a mismatch in the programmed CEDV coefficients for the specific cells used. is a specialized battery management system (BMS) integrated

Hybrid Gauging Technology

: The bq40370 uses a hybrid approach, combining Impedance Track (IT) and CEDV (Compensated End-of-Discharge Voltage) methods. This allows for highly accurate calculations of battery capacity and remaining run-time. Fault Reporting Capacity Jumps: A common symptom of
