Product Overview: TPS3617-50DGK by Texas Instruments

The TPS3617-50DGK is a highly reliable, low-power supervisory circuit designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is engineered to monitor power supplies in microprocessor and digital systems, providing a crucial safety net against system failures due to unstable or incorrect power supply voltages.

Encased in an 8-pin MSOP (DGK) package, the TPS3617-50DGK offers a compact solution for systems where space is at a premium. It is specifically designed to assert a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the system resets cleanly during power-up, power-down, and brown-out conditions.

Key Features:

• Voltage Monitoring: This supervisory circuit monitors a fixed-sense threshold voltage of 4.55V, which is ideal for 5V systems, ensuring that the device operates within the safe voltage range.
• Reset Time Delay: The TPS3617-50DGK includes an integrated time delay feature, which provides a delay before issuing a reset signal. This helps to avoid unnecessary resets due to transient voltage dips.
• Low Power Consumption: With a quiescent current of only 9µA (typical), the device is optimized for low-power applications, contributing to overall system power efficiency.
• Manual Reset Input: The inclusion of a manual reset input allows for a system reset to be initiated by external events or user interaction, providing additional flexibility and control.
• Temperature Range: The device operates over a wide temperature range from -40°C to +85°C, making it suitable for various industrial and commercial applications.

Applications:

The TPS3617-50DGK is versatile and can be used in a wide array of applications, including:

• Microprocessor or Microcontroller-based systems
• Portable/Battery-powered equipment
• Intelligent instruments
• Industrial controls
• Computers and servers
• Networking equipment

With its combination of features, the TPS3617-50DGK by Texas Instruments is an essential component for any system requiring reliable voltage supervision. It ensures that digital systems operate correctly and protects against the potential damage that can occur due to voltage anomalies.
