TPS3705-33DGNR Frequently Asked Questions (FAQs)

  • The DELAY pin is used to adjust the time it takes for the reset signal to be released after the voltage has risen above the threshold. This allows the user to customize the reset timing to their specific application.
  • The resistor values should be chosen to divide the input voltage to the desired threshold voltage. A good starting point is to use a 1:1 ratio (e.g., R1 = R2) and adjust from there. The datasheet provides a formula to calculate the resistor values.
  • The main difference is the threshold voltage: 3.3V for the TPS3705-33DGNR and 3.0V for the TPS3705-30DGNR. Choose the part that matches your system's voltage requirements.
  • Yes, the TPS3705-33DGNR is suitable for battery-powered devices. It has a low quiescent current (IQ) of 10 μA, making it suitable for battery-powered applications where power consumption is a concern.
  • Use a capacitor (e.g., 10 nF) between the RESET pin and GND to filter out any noise or glitches on the reset signal. This ensures a clean reset signal to the microcontroller or other devices.
