  2. RESET: Active-low reset output
  3. VDD: Positive supply voltage input

Functional Features

  • Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
  • Provides a programmable delay before asserting the reset signal.
  • Offers hysteresis to prevent false triggering due to noise or voltage fluctuations.
  • Low quiescent current consumption for power-sensitive applications.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Programmable delay feature enables customization for specific application requirements. - Low power consumption extends battery life in portable devices. - Small package size facilitates space-constrained designs.

Disadvantages: - Limited reset timeout period may not suit all applications requiring longer delays. - Single threshold voltage may not be suitable for systems with multiple voltage rails.

Working Principles

The TPS3809L30DBVT operates by continuously monitoring the supply voltage. When the voltage falls below the threshold voltage, the reset output is asserted low. The delay period can be programmed using an external capacitor connected to the CT pin. Once the delay period elapses, the reset output returns high.
