BQ25756ERRVR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and placement guide in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
  • The BQ25756ERRVR has a programmable charging profile, and Texas Instruments provides a charging profile calculator tool to help optimize the charging profile for specific battery chemistries. Additionally, the datasheet provides guidelines for setting the charging voltage and current limits.
  • The BQ25756ERRVR can handle input voltages up to 24V, but it's essential to ensure that the input voltage does not exceed the absolute maximum rating of 26V to prevent damage to the IC.
  • The BQ25756ERRVR has built-in OVP and UVP features, but they require external resistors and capacitors to set the threshold voltages. The datasheet provides a detailed description of how to implement OVP and UVP, and Texas Instruments also provides an application note with examples and calculations.
  • Yes, the BQ25756ERRVR is compatible with USB-C PD controllers, and Texas Instruments provides an application note that describes how to implement a USB-C PD charger using the BQ25756ERRVR and a PD controller.
