TPS3825-33DBVR by Texas Instruments

The TPS3825-33DBVR is a highly reliable, low-power supply voltage supervisor designed by Texas Instruments to ensure proper system operation during power-up, operation, and power-down. This integrated circuit (IC) is specifically engineered to monitor the supply voltage of microprocessors (μPs), microcontrollers (MCUs), and other voltage-sensitive systems, providing an essential component for a wide range of electronic applications.

This voltage supervisor comes in a compact SOT-23-5 package, making it suitable for space-constrained applications. It is characterized for operation over a temperature range of -40°C to +85°C, ensuring reliable performance across various environmental conditions. The device features a fixed-sense threshold voltage of 3.3V, which is a common voltage level for many digital systems, making it an ideal choice for monitoring 3.3V power supplies.

One of the key features of the TPS3825-33DBVR is its built-in watchdog timer, which provides an additional layer of system reliability. The watchdog timer can be used to reset the system in case of software lock-up, ensuring the system continues to operate correctly. Additionally, the device offers a manual reset input, which allows for an external signal to initiate a system reset, providing designers with flexibility in system control and management.

The TPS3825-33DBVR also includes a reset time delay, which can be programmed by an external capacitor. This feature allows designers to set the duration of the reset signal according to the specific needs of their system, ensuring that the system has adequate time to stabilize after a power-up or during a brown-out condition.

Overall, the TPS3825-33DBVR is a robust and versatile voltage supervisor that provides critical monitoring and control functions for electronic systems. Its low power consumption, programmable features, and small package size make it an excellent choice for applications ranging from portable devices to complex digital systems where reliable voltage supervision is essential.
