Introducing the TPS3110K33DBVT from Texas Instruments

The TPS3110K33DBVT is a precision supply voltage supervisor from the renowned semiconductor manufacturer, Texas Instruments. This device is designed to provide microprocessor supervisory functions by monitoring the supply voltage of digital systems. It ensures that the system operates reliably within specified voltage thresholds.

With a fixed-sense threshold voltage of 3.3V, the TPS3110K33DBVT is an ideal choice for systems that run on a standard 3.3V power rail. It is particularly suited for battery-powered equipment, portable devices, and other applications where power conditions need to be precisely monitored to prevent data corruption or hardware damage due to inappropriate voltage levels.

One of the key features of the TPS3110K33DBVT is its power-on reset control. This feature guarantees that the system's microprocessor (or microcontroller) is held in reset until the supply voltage reaches a stable and acceptable level during power-up. After this point, the reset signal is maintained for a specified period, ensuring the processor starts in a known state, which is critical for system integrity and reliability.

The device is offered in a compact SOT-23-6 package, making it suitable for space-constrained applications. Its small footprint does not compromise its performance; the TPS3110K33DBVT provides a low supply current, which is beneficial for power-sensitive designs. Additionally, it has a manual reset input that allows for a system reset to be initiated by external events or user interaction.

The TPS3110K33DBVT also features a watchdog timer that monitors the activity of the system. If the system becomes unresponsive or deviates from expected operation, the watchdog timer can reset the system, thereby aiding in the recovery from fault conditions.

With its combination of voltage supervision, manual reset, and watchdog functionality, the TPS3110K33DBVT from Texas Instruments is a versatile and reliable solution for system management. It ensures that digital systems maintain operation within safe voltage levels, safeguarding against data loss and hardware malfunction, which is critical for maintaining the integrity and longevity of electronic systems.
