TPS3126E15DBVT - Texas Instruments Voltage Supervisor IC

The TPS3126E15DBVT is a compact, low-power voltage supervisor device designed and manufactured by Texas Instruments. This IC is specifically engineered to provide precision voltage monitoring, typically for systems that require a controlled start-up and shutdown procedure to ensure data integrity and prevent damage to the system.

The TPS3126E15DBVT offers a fixed-sense threshold voltage of 1.5V, which is monitored against the supply voltage (VDD). This threshold is highly precise, making it suitable for applications that demand consistent and reliable operation. When the VDD falls below the 1.5V threshold, the reset output is triggered, which remains active until VDD rises above the threshold plus the hysteresis value, ensuring a clean and glitch-free reset signal.

Packaged in a 5-pin SOT-23 (DBVT) package, the TPS3126E15DBVT is designed for space-constrained applications. It is ideal for portable and battery-powered electronics, where size and power consumption are critical considerations. The device consumes only a low supply current, which is typically 9 µA, making it highly efficient for power-sensitive designs.

One of the key features of the TPS3126E15DBVT is its built-in watchdog timer, which forces a system reset if the supervisory circuit does not detect a periodic signal within a preset timeout period. This functionality is crucial for systems that need to recover from software lock-up or other faults without manual intervention.

The TPS3126E15DBVT operates over a wide temperature range from -40°C to +85°C, accommodating a variety of industrial and commercial application environments. Its robust design ensures that it can withstand harsh conditions while maintaining accurate voltage supervision.

In summary, the TPS3126E15DBVT from Texas Instruments is a reliable and efficient solution for system voltage supervision, offering precision monitoring with low power consumption in a small package, making it an excellent choice for a wide range of applications.
