A good PCB layout for the ACPL-021L-500E involves keeping the input and output circuits separate, using a ground plane, and minimizing the length of the input and output traces. It's also recommended to use a shielded cable for the input and output connections.
To ensure reliability in high-temperature applications, it's essential to follow the recommended operating temperature range of -40°C to 100°C, and to provide adequate heat sinking and thermal management. Additionally, consider using a thermally conductive material for the PCB and ensuring good airflow around the device.
The maximum allowable voltage imbalance between the input and output of the ACPL-021L-500E is ±1 kV. Exceeding this limit can cause damage to the device.
The ACPL-021L-500E is designed for low-frequency applications up to 100 kHz. While it may work at higher frequencies, its performance and reliability may degrade. For high-frequency applications, consider using a different isolator or consulting with a Broadcom engineer.
To troubleshoot issues with the ACPL-021L-500E, start by checking the input and output voltage levels, ensuring they are within the recommended range. Verify that the device is properly powered and that the input and output circuits are properly connected. If issues persist, consult the datasheet and application notes or contact Broadcom support.
