Product Overview: TPS3307-18DGN from Texas Instruments

The TPS3307-18DGN is a state-of-the-art supervisory circuit designed and manufactured by Texas Instruments, a global semiconductor company that specializes in developing integrated circuits and embedded processors. This product is part of Texas Instruments' extensive range of power management solutions, specifically tailored for monitoring voltage levels and system health in microprocessors, microcontrollers, and other digital systems.

Encased in an 8-pin MSOP (Mini Small Outline Package), the TPS3307-18DGN is compact and suitable for space-constrained applications. It is designed to provide triple voltage supervision, making it ideal for systems that require monitoring of multiple supply voltages simultaneously. Each of the three supervisors has a fixed-sense threshold voltage, with the -18DGN variant specifically designed to monitor a 1.8V power supply.

Key Features

• Triple Voltage Monitoring: Ensures that three separate supply voltages are within their specified ranges, improving system reliability and safety.
• Low Supply Current: With a typical supply current of only 40 µA, the device has minimal impact on the overall power consumption of the system.
• Programmable Time Delay: Offers an adjustable time delay for the reset signal, providing flexibility to cater to different system requirements.
• Manual Reset Input: Allows for an external signal to initiate a system reset, giving additional control to the user.
• Temperature Range: Operates over a wide temperature range from -40°C to +85°C, suitable for industrial environments.

Applications

The TPS3307-18DGN is versatile and can be used in a variety of applications, including:

• Industrial control systems
• Embedded processors and microcontrollers
• Networking equipment
• Portable and battery-powered electronics

With its robust design and precision voltage monitoring, the TPS3307-18DGN from Texas Instruments is a reliable solution for system designers looking to enhance the operational stability of their digital systems. Its small footprint and low power consumption make it an excellent choice for power-sensitive applications.
