TPS3110K33DBVRG4

The TPS3110K33DBVRG4 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. Here’s a detailed description of its features and specifications:

Key Features:

1. Voltage Monitoring: The TPS3110K33DBVRG4 monitors the supply voltage and ensures that the voltage remains within a specified range. It is particularly useful in applications where a stable power supply is critical for the reliable operation of digital circuits.

2. Reset Output: The device provides a reset output signal that is asserted when the supply voltage drops below the threshold level. This reset signal can be used to reset microcontrollers, FPGAs, or other digital logic devices, ensuring they start up correctly when power is restored.

3. Threshold Voltage: The TPS3110K33DBVRG4 is designed to monitor a specific threshold voltage of 3.3V. This makes it suitable for applications powered by 3.3V systems, which are common in many modern electronic devices.

4. Active-Low Reset: The reset output is active-low, meaning that it goes low (0V) when a reset condition is detected. This is a common configuration that allows easy interfacing with most digital logic devices.

5. Debounce Time: The device includes a built-in debounce time to prevent false triggering of the reset signal due to transient voltage fluctuations. This feature enhances the reliability of the reset function.
