BQ25672RQMR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. The datasheet provides a recommended layout, but it's essential to follow good PCB design practices to minimize noise and ensure proper operation.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value. The datasheet provides guidelines for inductor selection, but it's crucial to consider the specific application requirements and operating conditions.
  • The BQ25672RQMR can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range (4.5V to 12V) for optimal performance and to prevent damage to the device.
  • The BQ25672RQMR has a programmable charging profile using the I2C interface. Use the TI-provided software tools or consult the datasheet for specific register settings to configure the charging profile according to your application requirements.
  • The EN (enable) pin is used to enable or disable the charging function. Tie the EN pin to a logic high (VCC) to enable charging or a logic low (GND) to disable charging. You can also use the EN pin to implement a power-saving feature by disabling charging when the battery is fully charged.
