STMicroelectronics recommends a PCB layout with a thermal pad connected to a large copper area on the top and bottom layers to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.
To ensure reliable operation at high temperatures, it's essential to follow the recommended thermal design guidelines, use a suitable heat sink, and ensure good airflow around the device. Additionally, consider derating the device's power dissipation according to the temperature derating curve provided in the datasheet.
The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, for reliable operation, it's recommended to keep the input voltage within the recommended operating range of 3.3V to 5V.
Yes, the BUL1403ED can be used as a high-side switch. However, it's essential to ensure that the input voltage is within the recommended operating range and that the device is properly biased to prevent latch-up or other unwanted behavior.
To protect the device from ESD and overvoltage events, it's recommended to use external protection devices such as TVS diodes or ESD protection arrays. Additionally, follow proper PCB design and layout guidelines to minimize the risk of ESD damage.
