The following are the recommended layout guidelines:
- Ensure the input filters to the VC1 and VC2 pins are as close to the IC as possible to improve noise immunity.
- If the OUT pin is used to control a high current path, for example: to blow a chemical fuse, then care should be taken to ensure the high current path creates minimal interference of the BQ29209-Q1 voltage sense inputs.
- The input RC filter on the VDD pin should be close to the terminal of the IC.
