The TPS3803G09DBVR is a state-of-the-art supervisory circuit developed by Texas Instruments, designed to provide precision voltage monitoring to ensure reliable operation of microprocessors and digital systems. This compact and efficient device comes in a DBVR package, which is a small outline transistor (SOT-23) that is both space-saving and ideal for surface-mount technology (SMT).
Key Features
- Voltage Supervision: The TPS3803G09DBVR monitors a fixed voltage threshold of 0.9V, making it suitable for low-voltage applications that require precise voltage supervision to prevent data corruption or system failures.
- Reset Output: It features an active-low reset output, which provides a clear and assertive signal to the host system when the monitored voltage falls below the threshold, ensuring a safe system reset.
- Low Power Consumption: With its low quiescent current, the device is an excellent choice for battery-powered and portable applications where power efficiency is critical.
- Manual Reset: An additional manual reset input allows for an external override, giving the user direct control to initiate a system reset when necessary.
- High Accuracy: The TPS3803G09DBVR offers high threshold accuracy, enabling reliable monitoring and reset functionality even under tight tolerance conditions.
