TPS3780BDBVR Frequently Asked Questions (FAQs)

  • The recommended layout for the TPS3780BDBVR 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 digital 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 value between 1 kΩ and 10 kΩ is recommended.
  • The DELAY pin is used to delay the reset signal output after a power-on event. This allows the power supply to stabilize before the reset signal is released. The delay time is set by an external capacitor connected to the DELAY pin. The datasheet provides a formula to calculate the delay time based on the capacitor value.
  • No, the TPS3780BDBVR is not designed to operate with power supply voltages higher than 5.5V. Exceeding the maximum recommended voltage can cause damage to the device. If a higher voltage is required, consider using a voltage regulator or a different reset IC.
  • To ensure a correct reset during a power-on event, make sure that the power supply voltage rises slowly enough to allow the internal reference voltage to stabilize before the reset signal is released. A slow power supply ramp-up time of around 1-10 ms is recommended.
