The TPS3306-33DGK is a sophisticated, dual-channel supervisory circuit designed by Texas Instruments to monitor power supply functionality and processor activity, ensuring reliable system operation. This integrated circuit is particularly suitable for DSP and processor-based systems where precise power supply monitoring is critical.

Key Features

• Voltage Supervision: The TPS3306-33DGK provides 3.3V fixed-sense threshold voltage for precise monitoring and control of power supply levels.
• Dual Supervisory Circuits: It includes two independent voltage supervisors, enhancing system reliability through redundancy and enabling monitoring of multiple voltages or systems simultaneously.
• Manual Reset Input: A manual reset input allows for an external trigger to initiate a system reset, providing additional control to system operators or in the event of software malfunctions.
• Watchdog Timer: An integrated watchdog timer ensures the system processor operates as expected, and if not, it can trigger a system reset to recover from potential fault conditions.
• Power-On Reset Generator: The device generates a power-on reset pulse when supply voltages are established, ensuring that the system starts in a known state.
• Low Supply Current: Designed for power-sensitive applications, the TPS3306-33DGK operates with a low supply current, minimizing its impact on the overall power consumption of the system.

Applications

The TPS3306-33DGK is ideal for a wide range of applications, including:

• Industrial control systems
• Telecommunication equipment
• Portable/battery-powered electronics
• Networking hardware such as routers and switches
• Automotive systems
