TPS3707-25DGNRG4 - Texas Instruments

The TPS3707-25DGNRG4 is a highly precise supply voltage supervisor designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is engineered to provide a critical system monitoring function by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold. It is ideal for managing microprocessor and microcontroller power supply systems, ensuring that your digital systems operate reliably within their voltage parameters.

This supervisor comes in an 8-pin MSOP (DGN) package and features a fixed-sense threshold voltage of 2.5V, which is suitable for a variety of low-voltage applications. The TPS3707-25DGNRG4 offers a unique combination of low supply current and high accuracy, with a threshold voltage accuracy of ±1.5% at 25°C, making it a perfect choice for systems that require precise voltage monitoring without a significant power burden.

Key features of the TPS3707-25DGNRG4 include:

• Supply voltage supervision range tailored for 2.5V-powered systems.
• Low supply current of 6.5 µA (typical), which is advantageous for power-sensitive applications.
• Manual reset input, providing an external override for the reset signal.
• Watchdog timer functionality to ensure system responsiveness and recovery.
• Reset time delay of 20 ms (minimum), allowing the system enough time to stabilize after a voltage drop before resuming operation.
• Open-drain RESET output, which supports wired-OR connections and provides flexibility in interfacing with different logic levels.

The TPS3707-25DGNRG4's robust design also includes overtemperature and overcurrent protection, enhancing the reliability of the overall system. This voltage supervisor is commonly employed in a wide range of applications, from consumer electronics to industrial control systems, where maintaining correct operation during power fluctuations is critical.

With the TPS3707-25DGNRG4, Texas Instruments continues to demonstrate its commitment to high-quality, reliable components that meet the stringent demands of modern electronic systems. Whether you're designing a new product or upgrading an existing one, this voltage supervisor is an excellent choice for maintaining system integrity through precise voltage monitoring.
