Product Overview: TPS3824-30DBVT

The TPS3824-30DBVT from Texas Instruments is a highly reliable voltage supervisor designed to maintain system integrity in various electronic applications. This compact, low-power integrated circuit (IC) is engineered to monitor the supply voltage of digital systems, ensuring that the voltage remains within specified thresholds for proper operation.

Featuring a 3.0V fixed-sense threshold voltage, the TPS3824-30DBVT is ideal for managing 3.3V powered systems. It provides a critical layer of protection by asserting a reset signal whenever the monitored voltage drops below the acceptable range. The reset output remains active until the supply voltage returns to a stable level above the threshold, plus a hysteresis to prevent erratic reset operation.

This device comes in a compact SOT-23-5 package, making it suitable for space-constrained applications. Its small footprint does not compromise its performance or reliability, as it includes a built-in watchdog timer that can be disabled if not required. The watchdog feature further enhances system reliability by ensuring that the system's microcontroller is operating correctly.

The TPS3824-30DBVT is characterized for operation over a wide temperature range of –40°C to +85°C, allowing it to perform reliably in diverse environments. This voltage supervisor is a versatile solution for a broad range of applications, including portable electronics, computers, data storage, and industrial control systems, where maintaining voltage integrity is critical.

Key features of the TPS3824-30DBVT include a manual reset input, which allows for an external signal to trigger the reset function, providing additional system control. The device also boasts a low supply current of 15 µA (typical), making it an energy-efficient choice for battery-powered applications.

In summary, the TPS3824-30DBVT from Texas Instruments is an essential component for system designers looking to enhance the reliability and stability of their digital systems. Its precise voltage monitoring, integrated watchdog timer, and low power consumption make it a robust solution for safeguarding electronic systems against voltage anomalies.
