Product Overview: TPS3808G25DRVR from Texas Instruments

The TPS3808G25DRVR is a high-precision programmable delay supervisor from Texas Instruments, designed to provide reliable monitoring of voltage supplies in digital systems. This device is particularly suitable for applications that require an accurate and programmable power-on reset (POR) delay to ensure system stability during power-up sequences.

Key Features:

• Voltage Monitoring: The TPS3808G25DRVR monitors a fixed voltage threshold of 2.5V, making it ideal for supervising 2.5V power rails. It ensures that the system voltage is stable before allowing the processor or digital system to start its operations.
• Programmable Delay: Users can program the reset delay time via an external capacitor, which provides flexibility in setting the power-on reset timing to match specific system requirements.
• Low Quiescent Current: With a very low quiescent current of typically 3 µA, this supervisor IC is perfect for power-sensitive applications, helping to extend battery life in portable devices.
• Manual Reset Input: The device includes a manual reset input that allows the reset to be triggered with an external signal, offering an additional layer of system control.
• Watchdog Timer: A built-in watchdog timer ensures that the system operates correctly by resetting the system if the watchdog is not periodically refreshed, thus providing an extra safety mechanism against system failure.
• Small Form Factor: The TPS3808G25DRVR comes in a tiny 6-pin SON package, which is advantageous for space-constrained applications.

Applications:

The TPS3808G25DRVR is versatile and can be used in a variety of applications, including:

• Portable and battery-powered equipment
• Microcontroller and processor-based systems
• Industrial controls
• Networking equipment
• Medical devices

With its precision voltage monitoring and programmable delay, the TPS3808G25DRVR is an excellent choice for designers looking to enhance system reliability and performance. Texas Instruments' commitment to quality ensures that this voltage supervisor will provide a robust solution for managing power-up sequences in a wide range of electronic products.
