A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise coupling.
Ensure the input voltage (VIN) is within the recommended range (2.7V to 5.5V). Use a stable voltage regulator and decouple the input with a 10uF capacitor to minimize noise.
The maximum current draw is 150mA. However, it's recommended to keep the current draw below 100mA to ensure reliable operation and minimize heat generation.
Use a TVS diode or a zener diode to protect the input from overvoltage. Add a 1kΩ resistor in series with the input to limit the current in case of an ESD event.
The SI2101-TP is rated for operation up to 85°C. However, it's recommended to derate the device's performance and consider thermal management for high-temperature applications.
