TPS3823-33DBVR Typical application Circuitry

The TPS3823-33DBVR is part of the TPS382x family of voltage supervisors from Texas Instruments (TI). This family is designed to monitor the power rails in digital systems and provide a reset signal under certain conditions. The TPS3823-33 variant specifically monitors a 3.3V rail, as indicated by the "33" in its part number.

Description:

The TPS3823-33DBVR is a voltage supervisor that monitors a system voltage and asserts a reset if the system voltage goes below a predetermined threshold. It's intended to ensure proper system initialization and operation during power-up, power-down, and brown-out conditions.

Key Features:

1. Voltage Threshold: The TPS3823-33 monitors a 3.3V supply, as indicated by the "33".

2. Manual Reset Input (MR): This input allows an external trigger to initiate a reset, providing an additional layer of flexibility and control. This can be tied to a push-button, for instance.

3. Watchdog Timer: Some variants in the TPS382x family, including the TPS3823, come with a watchdog timer. This timer will trigger a reset if the connected microcontroller or processor doesn't "pat" or "kick" the watchdog within a specified time period. This feature ensures that if the system hangs or becomes unresponsive, a reset will be triggered.

4. Reset Output: An output that becomes active (typically goes low) when the monitored voltage goes below the threshold or when the watchdog timer is not periodically reset. It remains active for a predetermined timeout period after the voltage rises above the threshold or the watchdog is properly serviced.

5. Low Supply Current: These devices are designed for minimal power consumption and typically feature low quiescent currents.

6. Compact Package: The "DBVR" in the part number indicates that it comes in a SOT-23 package, a small surface-mount package suitable for space-constrained designs.

Applications:

Given its features, the TPS3823-33DBVR is ideal for:

- Microprocessor or microcontroller systems needing voltage supervision and/or a watchdog timer.

- Systems that require manual reset capabilities.

- Battery-powered devices.

- Portable electronics.

- Communication equipment.

For a comprehensive understanding of the TPS3823-33DBVR, including its electrical characteristics, recommended operating conditions, and more, it's always best to refer directly to the device's datasheet provided by Texas Instruments.
