BQ79656-Q1: Battery monitor selection help.

Part Number: BQ79656-Q1
Other Parts Discussed in Thread: BQ76930, BQ76PL455A


I am looking for a basic battery monitor, but am not sure which is my best option. Can you help point me to some that might work well? I have a few questions and requirements.

  1. We have a high current and small size application 100A+ that makes current sensing and in line FETs not feasible. For battery monitors with those items in the reference designs (Ex: BQ76930), do they require shunt resistors and in line FETs, or are they only optional?



Must have

  1. 7 Lipo cells. Ability for future expansion is nice.
  2. 85C+ rating
  3. Low/no power mode for storage.
  4. In stock.

Nice to have (Listed in priority)

  1. Internal cell balancing.
  2. Small design footprint.
  3. Reference designs with BOM
  4. Auto or better rating.
  5. External. Temperature sensing.
  6. Design files/gerbers available.

Thank you,
