TPS3307-18DGNR

The TPS3307-18DGNR is a voltage supervisor and reset IC manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. This ensures that the system operates reliably and prevents erratic behavior during power-up, power-down, or brownout conditions.

Key Features:

1. Voltage Monitoring: The TPS3307-18DGNR monitors a supply voltage range, typically around 1.8V, making it suitable for low-voltage applications. It can detect when the voltage drops below a predetermined threshold.

2. Reset Output: The device provides a reset output signal that is active low. This signal is asserted when the monitored voltage falls below the threshold, ensuring that the connected microcontroller or digital logic does not operate under unsafe voltage conditions.

3. Debounce Time: The TPS3307-18DGNR includes a built-in delay (or debounce) feature that prevents false resets due to transient voltage fluctuations. This delay can be configured to ensure that the reset signal remains active for a sufficient duration to allow the system to stabilize.

4. Low Power Consumption: The device is designed to operate with low power consumption, making it ideal for battery-powered applications. This feature helps extend the battery life of portable devices.

5. Wide Operating Temperature Range: The TPS3307-18DGNR is rated for a wide operating temperature range, typically from -40°C to +125°C, making it suitable for use in various environments, including industrial and automotive applications.

6. Small Package Size: The IC is available in a compact package (DGN), which is advantageous for space-constrained designs. The small footprint allows for easy integration into printed circuit boards (PCBs).

7. Applications: The TPS3307-18DGNR is commonly used in applications such as microcontroller reset circuits, power management systems, automotive electronics, and any system requiring reliable voltage monitoring and reset functionality.

Electrical Characteristics:

• Supply Voltage Range: The device typically operates within a specified voltage range, ensuring compatibility with various power supply systems.
• Reset Threshold Voltage: The reset threshold is set to trigger at a specific voltage level, which can be selected based on the application requirements.
• Output Drive Capability: The reset output can drive external components, providing flexibility in interfacing with other parts of the system.

Conclusion:

The TPS3307-18DGNR from Texas Instruments is a robust and reliable voltage supervisor and reset IC that plays a critical role in ensuring the stability and reliability of electronic systems. Its combination of low power consumption, wide operating temperature range, and compact design makes it an excellent choice for a variety of applications where voltage monitoring and reset functionality are essential.
