TPS3808G33MDBVREP

The TPS3808G33MDBVREP is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide reset signals to microcontrollers and other digital devices, ensuring reliable operation during power-up, power-down, and brownout conditions.

Key Features:

1. Voltage Monitoring: The TPS3808G33MDBVREP specifically monitors a supply voltage of 3.3V. It is designed to detect when the voltage falls below a certain threshold, which is critical for preventing erratic behavior in digital circuits.

2. Reset Output: The IC provides a reset output signal that is asserted low when the monitored voltage drops below the threshold. This reset signal is released once the voltage returns to a stable level, ensuring that the connected microcontroller or digital device does not operate under unsafe voltage conditions.

3. Low Supply Current: The device operates with a low supply current, making it suitable for battery-powered applications where power efficiency is crucial.

4. Wide Operating Voltage Range: The TPS3808G33MDBVREP can operate over a range of supply voltages, typically from 1.0V to 5.5V, allowing it to be used in various applications.

5. Temperature Range: It is designed to function effectively over an extended temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

6. Compact Package: The IC is available in a small, surface-mount package (such as the SOT-23), which is advantageous for space-constrained designs.

7. Adjustable Reset Timeout: The reset timeout period can be configured, allowing designers to set how long the reset signal remains active after the voltage returns to normal levels.

8. Hysteresis: The device includes built-in hysteresis to prevent false triggering due to noise or rapid fluctuations in the supply voltage.

Applications:

The TPS3808G33MDBVREP is commonly used in various applications, including:

• Microcontroller and microprocessor reset circuits
• Power management systems
• Battery-operated devices
• Automotive electronics
• Industrial control systems

Conclusion:

Overall, the TPS3808G33MDBVREP from Texas Instruments is a reliable and efficient voltage supervisor that plays a crucial role in ensuring the stability and safety of electronic systems by monitoring supply voltages and providing necessary reset signals. Its features make it a versatile choice for a wide range of applications in both consumer and industrial electronics.
