BQ2023PW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the BQ2023PW placed close to the battery, and the voltage sense pins (VSENSE and VBAT) connected to the battery with short, low-impedance traces. This minimizes noise and ensures accurate voltage sensing.
  • The BQ2023PW has an internal POR and BOD circuitry that resets the device when the supply voltage falls below a certain threshold. To handle this, ensure that the power supply is stable and within the recommended operating range. You can also add external circuitry to filter out noise and voltage spikes.
  • The BQ2023PW's gas gauge has an accuracy of ±5% over the entire operating range. To handle battery aging, the device uses a learning cycle to adapt to changes in the battery's capacity over time. This learning cycle can be initiated manually or automatically based on the device's configuration.
  • Calibration involves setting the device's internal registers to match the specific battery characteristics. Texas Instruments provides a calibration procedure in the datasheet, which involves measuring the battery's capacity, voltage, and temperature. You can also use TI's Fuel Gauge Calibration Tool to simplify the process.
  • The BQ2023PW's internal temperature sensor has an accuracy of ±5°C. To improve accuracy, you can use an external thermistor or thermocouple connected to the device's TSENSE pin. This allows for more precise temperature measurement and compensation.
