Diodes Incorporated provides a recommended PCB layout in the application note AN-63, which includes guidelines for component placement, thermal management, and routing to minimize noise and ensure optimal performance.
The AS7815AT-E1 has a thermal pad on the bottom of the package, which should be connected to a thermal plane on the PCB to dissipate heat. A thermal interface material (TIM) can be used to improve thermal conductivity. Additionally, ensure good airflow around the device and avoid blocking the airflow with nearby components.
The maximum allowed voltage on the EN pin is 6V, as specified in the datasheet. Exceeding this voltage may damage the device. It's recommended to use a voltage limiter or a voltage divider to ensure the EN pin voltage remains within the specified range.
The AS7815AT-E1 is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If your application requires operation above 125°C, consider using a different device or implementing additional cooling measures to ensure reliable operation.
Diodes Incorporated provides a troubleshooting guide in the application note AN-63, which covers common issues and their solutions. Additionally, you can contact Diodes Incorporated's technical support team for assistance with specific issues.
