BQ40370 Report

• FAULT / STATUS pins assert to signal the MCU with encoded or multi-line signalling.
• Some versions use PWM or blink patterns; others use open-drain outputs that go low on fault.
• Clear and descriptive flags for OV, UV, OC, SC, THERM, and other conditions.

10. Test Procedures and Validation

• Functional tests:

  If you need: a specific schematic in PCB-ready format, example BOM with component values and footprints, timing diagrams from the exact datasheet, or an annotated PCB layout and Gerber guidance for a particular variant of bq40370, tell me which variant and I will produce that detailed deliverable. bq40370

• Oscillatory behavior near OV/UV:

  13. Firmware Integration Recommendations

  • 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.
