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 minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including voltage, current, and power dissipation. Additionally, consider using a heat sink or thermal management system to keep the junction temperature below the maximum rating of 150°C.
Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the internal ESD protection diodes.
While the DA228KT146 is not specifically designed for high-humidity environments, it can still be used in such conditions with proper precautions. Ensure the device is properly sealed, and consider applying a conformal coating to protect against moisture ingress.
To prevent damage or degradation, store the DA228KT146 in a dry, cool place (below 30°C and 60% RH) in its original packaging or an anti-static bag. Avoid exposing the device to direct sunlight, moisture, or extreme temperatures.
