Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the programmed threshold.
• Provides a manual reset input for immediate system reset.
• Programmable delay allows customization of the reset time delay.
• Low power consumption for energy-efficient applications.

Advantages

• Wide supply voltage range enables compatibility with various systems.
• Precise monitoring ensures reliable operation of microcontrollers and digital systems.
• Adjustable reset time delay accommodates different system requirements.
• Small package size (SOT-23-5) allows for space-saving designs.
• Low power consumption extends battery life in portable devices.

Disadvantages

• Limited threshold voltage options may not cover all voltage level requirements.
• Manual reset input may require additional external components for proper functionality.
• Operating temperature range may not be suitable for extreme environments.

Working Principles

The TPS3106E09DBVRG4 operates by comparing the supply voltage with the programmed threshold voltage. When the supply voltage falls below the threshold, the reset output is asserted, indicating a low-voltage condition. The manual reset input can also trigger an immediate system reset. The programmable delay feature allows users to set the time delay before the reset signal is released.

Detailed Application Field Plans

• Battery-powered devices: Ensures safe shutdown or system reset when the battery voltage drops below a certain level.
• Industrial control systems: Monitors power supply integrity and provides reset signals to microcontrollers in case of voltage fluctuations.
• Automotive electronics: Protects sensitive electronic components from voltage variations and initiates system resets if necessary.
• Home automation: Guarantees stable operation of smart home devices by monitoring the power supply and triggering resets when needed.
