TPS3823-30DBVT

The TPS3823-30DBVT 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 TPS3823-30DBVT monitors a specific voltage level, typically set at 3.0V. It ensures that the monitored voltage remains within acceptable limits, providing a reset signal if the voltage falls below the threshold.

2. Reset Output: The device features an active-low reset output (RESET), which is asserted when the monitored 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 (or debounce) time, which helps to filter out noise and prevent false triggering of the reset signal. This ensures that transient voltage dips do not inadvertently reset the system.

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, typically from -40°C to +125°C, ensuring reliability in harsh environments.

7. Package Type: The TPS3823-30DBVT is housed in a small, surface-mount package (DBV), which is ideal for space-constrained applications. The package dimensions are compact, allowing for easy integration into printed circuit boards (PCBs).

8. Applications: This voltage supervisor is commonly used in microcontroller-based systems, automotive electronics, industrial control systems, and any application where reliable power monitoring and reset functionality are required.

Electrical Characteristics:

• Threshold Voltage: 3.0V (typical)
• Reset Active Time: Typically a few milliseconds after the voltage returns to normal
• Supply Current: Low, typically in the microamp range
• Input Voltage Range: 1.0V to 5.5V

Conclusion:

The TPS3823-30DBVT from Texas Instruments is a reliable and efficient voltage supervisor that provides essential monitoring and reset functionality for digital systems. Its compact size, low power consumption, and robust performance make it an excellent choice for a wide range of electronic applications.
