TPS389025QDSERQ1 Frequently Asked Questions (FAQs)

  • The DELAY pin is used to adjust the time it takes for the voltage supervisor to assert the reset signal after a power-on event or a voltage drop. This allows the system to stabilize before the reset signal is released.
  • The threshold voltage should be chosen based on the minimum operating voltage of the system. It's recommended to choose a threshold voltage that is slightly higher than the minimum operating voltage to ensure the system is fully powered before the reset signal is released.
  • The main difference is the threshold voltage. The TPS389025QDSERQ1 has a threshold voltage of 2.5V, while the TPS389025QDSERQ1B has a threshold voltage of 2.7V. Choose the correct part based on the minimum operating voltage of your system.
  • Yes, the TPS389025QDSERQ1 can be used as a power-on reset circuit. The device will assert the reset signal during power-up and hold it until the voltage reaches the threshold voltage, ensuring the system is fully powered before the reset signal is released.
  • The reset timeout period can be calculated using the formula: t_reset = RDELAY * CDELAY, where RDELAY is the resistance connected to the DELAY pin and CDELAY is the capacitance connected to the DELAY pin.
