Product Overview: TPS3806I33DBVT from Texas Instruments

The TPS3806I33DBVT is a high-precision voltage detector designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This device is specifically engineered to monitor the supply voltage of microprocessors (μPs), microcontrollers (MCUs), and other voltage-sensitive systems. With its compact SOT-23-6 package, the TPS3806I33DBVT is an ideal choice for space-constrained applications that require accurate voltage supervision.

The TPS3806I33DBVT offers a fixed-sense threshold voltage of 3.3V, which is suitable for a variety of 3.3V-powered systems. It incorporates a time-delay feature that prevents false triggering due to transient conditions, ensuring stable system operation. This time delay is programmable via an external capacitor, allowing designers to tailor the supervisory circuit to their specific needs.

One of the key features of the TPS3806I33DBVT is its low quiescent current, which is critical for battery-powered and low-power applications. This characteristic helps in extending the battery life of portable devices by minimizing power consumption when the system is in standby mode.

Furthermore, the device offers a push-pull RESET output, which provides a definitive signal to the monitored processor or system whenever the supply voltage drops below the threshold. The RESET output remains active until the supply voltage returns to an acceptable level, plus the time delay period, ensuring that the system has adequate time to stabilize.

The TPS3806I33DBVT also features built-in hysteresis to prevent oscillations at the threshold voltage, contributing to the reliable operation of the end system. Its wide operating temperature range from -40°C to +85°C allows it to be used in various environmental conditions, from industrial to commercial applications.

In summary, the TPS3806I33DBVT from Texas Instruments is a robust and reliable voltage detector that offers precision monitoring with customizable delay options. Its low power consumption and small form factor make it an excellent choice for a wide range of applications that require dependable voltage supervision to protect sensitive electronic systems.
