The TPS3823-30DBVRG4 is a highly reliable, low-power supervisory circuit designed by Texas Instruments to monitor power supply and system voltages. Its primary function is to ensure that digital systems operate within specified voltage limits and to provide a reset signal whenever necessary. This component is essential for applications where precise voltage monitoring is critical for the performance and longevity of the system.

This device features a fixed-sense threshold voltage of 3.0V, which makes it suitable for monitoring 3.3V power supplies. With a very low quiescent current of approximately 15 µA, the TPS3823-30DBVRG4 contributes minimally to the overall power consumption of the system, making it an ideal choice for power-sensitive applications.

The supervisory circuit incorporates a manual reset input, enabling the user to trigger a system reset manually. This feature is particularly useful for system maintenance or in situations where an immediate system reboot is required without power cycling. The TPS3823-30DBVRG4 also offers a reset time delay, which can be programmed via an external capacitor to provide a reset signal for a specific duration after the monitored voltage has returned to an acceptable level.

Packaged in a small SOT-23-5 package, the TPS3823-30DBVRG4 is designed for compact PCB layouts and can be easily integrated into space-constrained designs. It is characterized for operation over a temperature range of -40°C to +85°C, which allows for deployment in a variety of environments and applications, including industrial, consumer, and computing devices.

The TPS3823-30DBVRG4 is a testament to Texas Instruments' commitment to providing robust and reliable power management solutions. Its precision voltage monitoring and low power consumption, combined with the convenience of a manual reset, make it a versatile component for safeguarding electronic systems.
