Product Overview: TPS3619-33DGK

The TPS3619-33DGK is a highly reliable, low-power supervisory circuit designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This supervisory circuit is engineered to monitor power supply and system voltages, ensuring that microprocessors and digital systems operate optimally within their voltage thresholds.

Contained in an 8-pin MSOP (DGK) package, the TPS3619-33DGK offers a fixed-sense threshold voltage of 3.3V, which is ideal for 3.3V-powered systems. It is designed to assert a reset signal whenever the VCC supply voltage drops below the 3.3V threshold, thus safeguarding the system from running under conditions that could lead to unpredictable behavior.

Key Features:

• Voltage Monitoring: Precise monitoring of 3.3V supply lines to ensure proper system reset functionality.
• Low Power Consumption: With a typical supply current of only 9 µA, it minimizes the power draw on the system, making it suitable for power-sensitive applications.
• Programmable Delay: The reset output delay can be programmed via an external capacitor, allowing designers to customize the reset timing to match specific system requirements.
• Manual Reset: The inclusion of a manual reset input provides an additional layer of system control, enabling users to manually initiate a system reset.
• Wide Operating Temperature Range: The device operates over a temperature range of -40°C to +85°C, ensuring reliable performance across various environmental conditions.

Applications:

The TPS3619-33DGK is versatile in its applications, suitable for a range of electronic systems that require precise voltage monitoring and reset functions. These include:

• Microprocessor or Microcontroller-based Systems
• Portable/Battery-Powered Equipment
• Industrial Controls
• Notebook Computers
• Medical Devices
• Networking Equipment

With its robust design and precision voltage monitoring capabilities, the TPS3619-33DGK from Texas Instruments is an essential component for ensuring system stability and reliability. Its small footprint and low power consumption make it an excellent choice for designers looking to enhance the operational integrity of their digital systems.
