The TPS3110K33DBVR is a highly reliable, low-power supervisory circuit designed by Texas Instruments to monitor power supplies in digital systems. It is intended to provide a significant level of system protection by asserting a reset signal whenever the VCC supply voltage falls below a predefined threshold, ensuring proper system initialization during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Monitor: This device keeps a watchful eye on the system voltage, featuring a precision voltage threshold of 3.3V, tailored for operations in a wide range of applications.
• Manual Reset: An additional manual reset input allows for external overriding, offering a direct way to initiate a system reset.
• Power-On Reset Generator: The built-in power-on reset generator ensures that the reset output remains active for a minimum of 200ms after VCC has risen above the reset voltage threshold, providing ample time for the system to stabilize.
• Low Supply Current: With a typical supply current of only 9μA, the TPS3110K33DBVR is optimized for low-power applications, contributing to overall energy efficiency.
• Reset Output: The device offers an active-low, push-pull reset output, which provides a robust reset signal that is compatible with most digital systems.
