BQ2004ESNTR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the BQ2004ESNTR placed close to the battery, and the sense resistors (Rs) placed close to the device. A 4-layer PCB is recommended to minimize noise and ensure accurate measurements.
  • Calibration involves setting the gain and offset for the voltage and current measurements. TI provides a calibration procedure in the datasheet, which involves measuring the voltage and current at multiple points and calculating the gain and offset values.
  • The BQ2004ESNTR has a maximum voltage rating of 25V, but it's recommended to operate it within the 10V to 20V range for optimal performance and accuracy.
  • The BQ2004ESNTR is designed for low-to-moderate current applications (up to 10A). For high-current applications, TI recommends using the BQ78350 or BQ79606A, which are designed for higher current ranges.
  • The BQ2004ESNTR has a sleep mode to reduce power consumption. To wake it up, apply a high pulse (>2.5V) to the WAKE pin for at least 100ns. The device will then enter its normal operating mode.
