TPS3780BDBVT Frequently Asked Questions (FAQs)

  • The recommended layout for the TPS3780BDBVT involves placing the device close to the power source, using short and wide traces for power and ground, and separating the analog and digital grounds. Additionally, it is recommended to use a solid ground plane and to avoid routing high-frequency signals under the device.
  • The value of the RSET resistor depends on the desired reset threshold voltage. The datasheet provides a formula to calculate the RSET value based on the desired reset threshold voltage and the internal reference voltage. Typically, a 1% tolerance resistor is recommended to ensure accurate reset threshold voltage.
  • The DELAY pin is used to delay the reset signal output during power-up. This is useful in systems where the power supply takes time to stabilize. The delay time is set by an external capacitor connected between the DELAY pin and ground. The datasheet provides a formula to calculate the delay time based on the capacitor value.
  • Yes, the TPS3780BDBVT can be used in systems with multiple power domains. However, it is essential to ensure that the device is powered from a stable voltage source and that the reset signal is properly synchronized across all power domains.
  • In cases where the input voltage is below the reset threshold voltage during power-up, the TPS3780BDBVT will not assert the reset signal. To handle this scenario, it is recommended to use a voltage supervisor with a lower reset threshold voltage or to add an external circuit to detect the power-up sequence and assert the reset signal manually.
