BQ33100: I2C/SMBus?

Part Number: BQ33100

Hi all,

A customer is seeing the BQ33100 sometimes return a wrong value, possibly related to the device's I2C/SMBus. What does the read/write transation look like for this device from the 0x00 ManufacturerAccess?, as it is not outlined in the datasheet? Will it look something like this?

  1. First byte: Slave Address + Write
  2. Second Byte: 0x00
  3. Repeated start?
  4. First byte: Slave Address + read/write (depending on the desired operation)
  5. Second + third bytes: 0x0021
  6. Stop?
