The TPS3620-33DGKT is a state-of-the-art supervisory circuit from Texas Instruments, designed to monitor power supplies in digital systems. It provides a crucial safety feature by asserting a reset signal whenever the VCC supply voltage falls below a predetermined threshold, ensuring the proper operation of microprocessors, microcontrollers, and other digital systems by preventing code execution errors during power-up, power-down, or brown-out conditions.

Key Features

• Precision Voltage Monitoring: This device is tailored to monitor a 3.3V supply voltage with a high degree of accuracy, ensuring reliable operation of the system it is protecting.
• Programmable Delay: It comes with an adjustable delay time that can be set by an external capacitor, which allows designers to customize the reset time delay to meet specific system requirements.
• Manual Reset Input: The TPS3620-33DGKT includes a manual reset input that enables a system reset to be initiated with an external push-button or logic signal, providing an additional layer of control.
• Open-Drain Reset Output: The reset output is open-drain, meaning it requires an external pull-up resistor. This design offers flexibility in interfacing with different logic levels and is suitable for wired-OR connections.
• Low Power Consumption: Designed for energy-sensitive applications, the device consumes minimal power, thereby contributing to the overall power efficiency of the system it is implemented in.
• Compact Package: Housed in an 8-pin MSOP (DGK) package, the TPS3620-33DGKT is suitable for space-constrained applications.
