Product Overview: TPS3808G12DBVTG4

The TPS3808G12DBVTG4 is a high-precision programmable delay supervisor from Texas Instruments designed to provide reliable monitoring of power supply and processor health in electronic systems. This voltage supervisor ensures that systems operate within safe voltage levels, thereby enhancing the longevity and stability of the application it is integrated into.

With a fixed-sense threshold voltage of 1.193V and an adjustable delay time from 1.25ms to 10s via an external capacitor, the TPS3808G12DBVTG4 allows for versatile and customizable monitoring solutions. It is particularly suitable for applications that require precise voltage supervision and a programmable time delay to avoid false triggering, such as portable and battery-powered equipment, industrial controls, and computing systems.

Key Features:

• Accuracy: The device boasts a high threshold voltage accuracy of ±0.5% at 25°C, ensuring precise monitoring and protection for sensitive electronics.
• Low Power Consumption: With a very low quiescent current of 6.5µA (typical), it is an ideal choice for battery-operated devices where power conservation is crucial.
• Manual Reset: The manual reset input provides a simple way to initiate a system reset, allowing for greater control over system operation.
• Watchdog Timer: An integrated watchdog timer further enhances system reliability by monitoring system activity and initiating a system reset in case of a malfunction or software lock-up.
• Supply Voltage Range: The device operates over a wide supply voltage range from 1.7V to 6.5V, catering to a broad spectrum of power requirements.
• Temperature Range: It is operational across an industrial temperature range of -40°C to 125°C, making it suitable for harsh environments.

Package and Availability:

The TPS3808G12DBVTG4 comes in a compact 6-pin SOT-23 package, which is ideal for space-constrained applications. Texas Instruments' commitment to quality ensures that this voltage supervisor is highly reliable and available for a wide range of industrial and commercial uses.

Whether you are designing a new system or upgrading an existing one, the TPS3808G12DBVTG4 offers an optimal solution for your voltage supervision needs, combining accuracy, flexibility, and low power consumption in a small package.
