BQ20Z75DBT Frequently Asked Questions (FAQ)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'Battery Fuel Gauge Design Guide' (SLUA451) and the 'PCB Layout Guidelines for Fuel Gauges' (SLUA452) application notes.

  • Calibration of the BQ20Z75DBT involves a series of steps, including initial calibration, learning, and adaptation. Refer to the 'Battery Fuel Gauge Calibration Guide' (SLUA453) application note for a detailed calibration procedure.

  • The accuracy of the BQ20Z75DBT fuel gauge depends on various factors, including the battery type, age, and health. Typically, the fuel gauge accuracy is ±5% over the entire state-of-charge (SOC) range. However, this can be improved with proper calibration and adaptation.

  • The BQ20Z75DBT is optimized for lithium-ion (Li-ion) batteries, but it can be used with other battery chemistries, such as lithium-polymer (Li-poly) or nickel-metal hydride (NiMH), with some modifications to the calibration and configuration. However, it's recommended to consult with Texas Instruments or a battery expert for specific guidance.

  • The BQ20Z75DBT has a built-in overcharge protection feature that can be enabled through the configuration registers. Additionally, an external overcharge protection circuit can be implemented using a voltage supervisor or a dedicated overcharge protection IC.
