A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the power and ground traces as short as possible and use a common mode filter to reduce EMI.
Use a reliable communication protocol such as SPI or I2C, and ensure that the clock frequency is within the recommended range. Also, use a pull-up resistor on the SDA line and a pull-down resistor on the SCL line.
The FXPS7115DS4T1 can operate in the temperature range of -40°C to 125°C. However, the device's performance may degrade at extreme temperatures.
The POR and BOR features are enabled by default. To handle them, ensure that the power supply is stable and within the recommended range. Also, use a capacitor on the VDD pin to filter out noise and ensure a clean power-on reset.
Use a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed as close as possible to the VDD pin. This will help to filter out noise and ensure a stable power supply.
