Product Overview: TPS3103K33DBVT by Texas Instruments

The TPS3103K33DBVT is a highly reliable and versatile supervisory circuit integrated circuit designed by Texas Instruments (TI), engineered to monitor power supply and system health in digital systems. It ensures that microprocessors and other digital systems operate within safe voltage levels and provides a controlled system reset in case of power failure or anomalies.

Key Features

  • Supply Voltage Monitoring: The device is adept at keeping a vigilant eye on the supply voltage, ensuring it does not dip below a critical threshold that could compromise system integrity.
  • Programmable Delay: It comes with a programmable time delay feature which provides flexibility in determining how long the system should wait before initiating a reset, allowing for customized system behavior based on specific requirements.
  • Low Supply Current: With a focus on energy efficiency, the TPS3103K33DBVT boasts a low supply current, making it an ideal choice for battery-operated and power-sensitive applications.
  • Manual Reset Input: The inclusion of a manual reset input gives users the ability to trigger a system reset manually, offering an additional layer of control over the system.
  • Temperature Range: It is designed to operate over a wide temperature range, which is critical for reliability in varying environmental conditions.


The TPS3103K33DBVT is suited for a broad range of applications, including:

  • Portable and battery-powered electronics
  • Microcontroller-based systems
  • Industrial controls
  • Embedded systems
  • Networking equipment
