7.2 Typical Application

Design 1: Adjustable Voltage Supervisor with Push-Button Functionality

A typical application for the TPS3899 is voltage rail monitoring with push-button functionality and specific timing requirements.

In this design application, the TPS3899DL01 is being used to monitor a 3.3V power rail and triggers a reset when the voltage drops below 2.9V or when the push-button is pressed. The reset output connects to an MCU for system resetting or servicing the push-button.
