Product Overview: TPS3825-33DBVRG4 by Texas Instruments

The TPS3825-33DBVRG4 is a state-of-the-art supervisory circuit developed by Texas Instruments, designed to ensure reliable operation of microprocessors (µPs) and other digital systems. This compact and efficient device provides a crucial function by monitoring the system's power supply voltage, asserting a reset signal whenever it detects a voltage that is out of the designated threshold range. This reset signal ensures that the µP and associated digital systems initialize in a known state, which is essential for maintaining system integrity and preventing erratic behavior.

Key Features:

• Voltage Monitoring: The TPS3825-33DBVRG4 is specifically tailored to monitor a fixed voltage threshold of 3.3V, making it an ideal choice for systems operating at this common supply voltage.
• Programmable Delay: It includes a programmable time delay feature, which provides designers with the flexibility to set the duration of the reset signal according to specific system requirements, ensuring that the system has adequate time to stabilize before normal operation resumes.
• Manual Reset: An additional manual reset input allows for an external trigger to initiate a system reset, granting further control to system operators or additional circuitry.
• Low Power Consumption: Designed with energy efficiency in mind, this device consumes minimal power, making it suitable for battery-powered and portable applications where power conservation is critical.
• Watchdog Timer: The integrated watchdog timer serves as an independent system monitor, which can reset the system in case of software or hardware malfunction, further enhancing system reliability.
• High Accuracy: The TPS3825-33DBVRG4 boasts a high threshold accuracy which ensures precise monitoring and reset activation, contributing to the overall stability of the system it is protecting.

Packaging and Availability:

The TPS3825-33DBVRG4 comes in a compact SOT-23-5 package, which is ideal for space-constrained applications. Texas Instruments ensures wide availability of this product, catering to diverse industrial, commercial, and consumer applications where reliable voltage supervision is required.

With its robust feature set and dependable performance, the TPS3825-33DBVRG4 by Texas Instruments is a premium choice for designers looking to enhance the reliability and operational safety of their digital systems.
