  • Pin 2: VDD (Supply Voltage)
  • Pin 3: RESET (Reset Output)

Functional Features

  • Monitors the supply voltage and asserts the reset output when it falls below the threshold voltage.
  • Provides a reset signal to the microcontroller or other digital devices to ensure proper initialization.
  • Offers fixed or adjustable reset timeout period for flexibility in different applications.
  • Low quiescent current consumption makes it suitable for battery-powered devices.
  • Precision monitoring ensures accurate detection of voltage variations.

Advantages

  • Small package size allows for space-efficient designs.
  • Wide supply voltage range enables compatibility with various systems.
  • Low power consumption prolongs battery life in portable applications.
  • Accurate monitoring prevents system malfunctions due to voltage fluctuations.
  • Flexible reset timeout options cater to different application requirements.

Disadvantages

  • Limited number of threshold voltage options may not cover all voltage levels required in certain applications.
  • Lack of additional features, such as hysteresis adjustment, may limit its suitability for specific use cases.

Working Principles

The TLV810MDBZR operates by continuously monitoring the supply voltage. When the voltage falls below the threshold voltage, the reset output is asserted, indicating a power failure or an out-of-range condition. The reset signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.
