TPS3823-30DBVR

The TPS3823-30DBVR 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 TPS3823-30DBVR monitors a specific voltage level, typically set at 3.0V. It ensures that the monitored voltage remains within a defined range, providing a reset signal when the voltage falls below the threshold.

2. Reset Output: The device features an active-low reset output (RESET), which is asserted when the supply voltage drops below the threshold. This output remains low for a specified duration after the voltage returns to normal, allowing the system to stabilize before resuming operation.

3. Debounce Time: The TPS3823 includes a built-in delay to prevent false triggering of the reset signal due to transient voltage dips. This debounce time can be adjusted based on the application requirements.

4. Low Supply Current: The IC is designed to operate with low supply current, making it suitable for battery-powered applications where power efficiency is critical.

5. Wide Operating Voltage Range: The TPS3823 can operate over a wide range of supply voltages, typically from 1.0V to 5.5V, making it versatile for various applications.

6. Temperature Range: The device is rated for operation over an extended temperature range, ensuring reliability in different environmental conditions.

7. Small Package Size: The TPS3823-30DBVR is housed in a compact 5-pin SOT-23 package, which is ideal for space-constrained designs.

Applications:

• Microcontroller and microprocessor reset circuits
• Power supply monitoring in consumer electronics
