Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. Additionally, it's recommended to use a star-configuration for the power supply and to keep the input and output traces short and away from each other.
The TLV1391CDBVR has a built-in POR and BOR circuitry. To handle these, ensure that the power supply is stable and within the recommended operating range. Also, add a capacitor between the VCC and GND pins to filter out noise and ensure a clean power-on reset.
The recommended input capacitance is 10nF to 100nF, and the recommended output capacitance is 10nF to 1uF. However, the optimal capacitance values may vary depending on the specific application and operating frequency.
To ensure EMC and reduce EMI, use a shielded enclosure, keep the analog and digital circuits separate, and use a common-mode choke or ferrite bead on the input and output lines. Additionally, ensure that the PCB layout is optimized for minimal radiation and that the device is properly grounded.
The recommended operating temperature range for the TLV1391CDBVR is -40°C to 125°C. However, the device can operate up to 150°C for short periods of time. Ensure that the device is properly heat-sinked and that the operating temperature is within the recommended range for optimal performance and reliability.
