BQ20Z70PW-V160 Frequently Asked Questions (FAQs)

  • 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 BQ20Z70PW-V160 involves setting the device's internal registers to match the characteristics of the battery. This can be done using the TI-provided software tools, such as the Fuel Gauge Calibration Tool (FGCT) or the Battery Management Studio (BMS).
  • The accuracy of the SOC measurement depends on various factors, including the quality of the calibration, the type of battery, and the operating conditions. Typically, the BQ20Z70PW-V160 can achieve an SOC accuracy of ±5% or better.
  • The BQ20Z70PW-V160 is optimized for lithium-ion batteries, but it can be used with other battery chemistries with some modifications. However, the accuracy and performance may vary, and additional calibration may be required.
  • The BQ20Z70PW-V160 has a built-in POR and BOR circuitry to ensure reliable operation. The POR is triggered when the device powers on, and the BOR is triggered when the supply voltage drops below a certain threshold. The device will automatically reset and recover when the power supply is restored.
