The TPS3808G01DBVR is an integrated circuit (IC) component developed by Texas Instruments. It is a supervisory circuit that monitors the voltage levels and generates a reset signal for microcontrollers, microprocessors, or other critical digital systems. This IC is commonly used in various electronic devices to ensure reliable and safe operation.
Key features of the TPS3808G01DBVR include:
1. Voltage Monitoring: The IC can monitor the voltage levels of the power supply to detect undervoltage and overvoltage conditions. It can accurately detect thresholds as low as 0.9V and as high as 5.5V.
2. Programmable Reset Delay: It allows users to set the reset delay time using an external capacitor. This feature allows customization based on the specific requirements of the system.
3. Power-On Reset (POR): The TPS3808G01DBVR generates a reset signal during power-up, ensuring that the system enters a known state at startup. This is crucial for devices that require reliable initialization.
4. Manual Reset Input: The IC provides an input pin for manually asserting a reset signal. This feature is useful during testing or system debugging when a manual reset is required.
5. Watchdog Timer: The TPS3808G01DBVR includes a watchdog timer function that monitors the system's activity and generates a reset signal if the system becomes unresponsive. This helps prevent the system from being stuck in an indeterminate state
