ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A 4-layer PCB with a solid ground plane and thermal vias is also recommended.
Implement thermal management techniques such as heat sinks, thermal interfaces, and airflow management. Ensure the device is operated within the recommended temperature range (TJ = -40°C to 150°C) and consider derating the device's power dissipation at high temperatures.
The BU91520KV-ME2 has built-in ESD protection diodes, but additional external protection measures such as TVS diodes or ESD arrays may be necessary depending on the application. Latch-up prevention can be achieved by following proper PCB design and layout guidelines, such as separating analog and digital circuits and using guard rings.
Yes, the BU91520KV-ME2 is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, ensure that the device is used within the recommended operating conditions and that the application meets the required safety and reliability standards.
Use a systematic approach to troubleshoot, starting with checking the power supply, input/output signals, and PCB layout. Utilize oscilloscopes, logic analyzers, and other diagnostic tools to identify the root cause of the issue. Consult ROHM's application notes and technical support resources for guidance.
