BQ32002DR Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and placing the BQ32002DR near the battery to minimize noise and EMI. A 10nF capacitor between VCC and GND is also recommended.
  • Use a high-accuracy voltage reference, ensure the sense resistors are matched and of low tolerance, and calibrate the device during manufacturing. Also, consider using a temperature sensor to compensate for temperature effects.
  • The maximum allowed voltage on the BAT pin is 4.5V. Exceeding this voltage may damage the device.
  • The POR and BOR are triggered by a power-on event or a brown-out condition. Ensure that the system design can handle these events, and consider adding external circuitry to filter out noise and glitches.
  • Yes, the BQ32002DR can be used with multiple battery chemistries, but the device's settings and calibration may need to be adjusted accordingly. Consult the datasheet and application notes for specific guidance.
