TPS3808G01DBVRG4

The TPS3808G01DBVRG4 is a voltage supervisor integrated circuit (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 or power-down conditions.

Key Features:

1. Voltage Monitoring: The TPS3808G01 can monitor a variety of supply voltages, making it suitable for a wide range of applications. It typically features a fixed voltage threshold, which can be selected based on the specific needs of the application.

2. Reset Output: The IC provides a reset output signal that is asserted low when the monitored voltage drops below the threshold. This output remains low for a specified duration after the voltage returns to normal levels, ensuring that the system has stabilized before resuming operation.

3. Low Supply Current: The device is designed to operate with low supply current, making it energy-efficient and suitable for battery-powered applications.

4. Wide Operating Voltage Range: The TPS3808G01 operates over a wide voltage range, typically from 1.0V to 5.5V, allowing it to be used in various electronic systems.

5. Temperature Range: The IC is rated for operation over an extended temperature range, which enhances its reliability in different environmental conditions.

6. Small Package Size: The TPS3808G01 is available in a compact SOT-23 package, which is ideal for space-constrained applications.

7. Adjustable Reset Timeout: The reset timeout period can be configured, allowing designers to tailor the reset behavior to their specific application requirements.
