SD1728 Frequently Asked Questions (FAQ)
-
STMicroelectronics recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the IC to ensure optimal thermal performance.
-
To ensure reliable operation at high temperatures, ensure proper heat sinking, use a thermal interface material, and follow the recommended PCB layout guidelines. Additionally, consider using a thermal sensor to monitor the device temperature.
-
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 below 5V.
-
The SD1728 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 PCB is properly grounded.
-
The recommended power-up sequence is to apply the power supply voltage (VCC) before applying the input signals. This ensures that the internal voltage regulators are properly initialized.
