TPS3110K33DBVR

The TPS3110K33DBVR is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide reset signals for microcontrollers and other digital devices. Here’s a detailed description of its features and specifications:

Key Features:

1. Voltage Monitoring: The TPS3110K33DBVR monitors the supply voltage and ensures that it remains within a specified range. It is particularly designed to monitor a 3.3V power supply.

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

3. Adjustable Reset Threshold: The reset threshold can be adjusted to suit different applications, allowing for flexibility in design.

4. Active Low Reset: The reset output is active low, meaning that it goes low when a reset condition is detected, which is a common configuration for many digital systems.

5. Debounce Time: The TPS3110K33DBVR includes a built-in debounce time to prevent false triggering of the reset signal due to transient voltage fluctuations.

6. Low Power Consumption: The device is designed to operate with low power consumption, making it suitable for battery-powered applications.

7. Temperature Range: The IC operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

8. Package Type: The TPS3110K33DBVR is available in a small, surface-mount package (DBV), which is ideal for space-constrained designs.

Electrical Characteristics:

• Supply Voltage Range: The device typically operates from a supply voltage of 2.5V to 5.5V.
• Reset Threshold Voltage: The reset threshold is typically set at 3.3V, with a specified tolerance.
• Reset Timeout: The reset signal remains asserted for a defined timeout period after the voltage returns to the normal operating range, ensuring that the system has stabilized before resuming operation.

Applications:

The TPS3110K33DBVR is commonly used in various applications, including:

• Microcontroller reset circuits
• Power management systems
• Automotive electronics
• Industrial control systems
• Consumer electronics

Conclusion:

The TPS3110K33DBVR from Texas Instruments is a versatile and reliable voltage supervisor IC that provides essential monitoring and reset functionality for digital systems. Its combination of low power consumption, adjustable thresholds, and robust performance makes it an excellent choice for a wide range of electronic applications.
