Working Principles

The TPS3808G25DBVTG4 is a voltage supervisor IC that monitors the supply voltage and generates reset signals to digital systems. It compares the monitored voltage with a programmable threshold voltage and asserts the reset output when the voltage falls below the threshold for a specified timeout period. The reset signal remains asserted until the voltage rises above the threshold or a manual reset input is triggered.

The TPS3808G25DBVTG4 finds applications in various fields, including:

1. Microcontroller Systems: Provides reliable power-on reset functionality to ensure proper initialization of microcontrollers.
2. Industrial Control Systems: Monitors supply voltages in industrial control systems to prevent erratic behavior during power fluctuations.
3. Battery-Powered Devices: Protects battery-powered devices from operating at low voltages, preventing potential damage or data corruption.
4. Automotive Electronics: Ensures stable operation of automotive electronic systems by monitoring supply voltages and generating reset signals if necessary.
5. Home Automation: Used in smart home devices to monitor power supply integrity and initiate system resets if required.
