STMicroelectronics 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 to reduce thermal resistance.
To ensure reliable operation at high temperatures, it's essential to follow the recommended thermal design guidelines, including a proper thermal pad connection, adequate heat sinking, and a maximum junction temperature (Tj) of 150°C. Additionally, consider derating the device's power dissipation at higher temperatures.
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 4.5V to 5.5V.
The BUH1015HI has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that the device is handled in a static-safe environment.
The recommended input capacitance for stable operation is 10nF to 100nF. This capacitance helps to filter out noise and ensure stable operation. However, the optimal capacitance value may vary depending on the specific application and noise environment.
