The TPS3305-33DGNG is a sophisticated, dual voltage supervisor from Texas Instruments, designed to monitor two system voltages simultaneously. This high-precision device is crucial for ensuring the reliability and stability of electronic systems by providing supervisory functions that are essential for proper system operation and power management.

Key Features:

• Voltage Supervision: The TPS3305-33DGNG is capable of supervising a 3.3V supply with a 1.5% threshold accuracy, ensuring that the system operates within safe voltage levels.
• Dual Voltage Monitoring: This device can monitor both a fixed voltage (VIT1) and an adjustable voltage (VIT2), allowing for versatility in a wide range of applications.
• Power-On Reset Generator: It includes an integrated power-on reset generator that provides a reset signal to the microcontroller for a programmable delay time after voltage levels are detected to be within the acceptable range.
• Manual Reset Input: A manual reset input allows for an external trigger to initiate a system reset, offering additional control and safety mechanisms.
• Low Supply Current: With a typical supply current of only 40 μA, the TPS3305-33DGNG is optimized for low-power applications.

Applications:

The TPS3305-33DGNG is ideal for a variety of applications that require reliable voltage supervision, including:

• Microprocessor, Microcontroller, or DSP systems
• Portable/Battery-Powered Equipment
• Industrial Controls
• Notebook/Desktop Computers
• Communications Equipment

Package and Quality:

The device comes in an 8-pin MSOP (DGNG) package, which is small and suitable for space-constrained applications. The TPS3305-33DGNG is also characterized for operation over a temperature range of -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions. Texas Instruments is known for its commitment to quality, and this product is no exception, meeting high industry standards for performance and reliability.
