The TLV809K33DBZR is a state-of-the-art voltage supervisor designed by Texas Instruments to ensure reliable operation of microprocessors and other voltage-sensitive devices. This compact and efficient component is essential for systems that require a precise monitoring of supply voltage to prevent data corruption, erratic operation, or damage to the system due to power fluctuations.

Key Features

• Supply Voltage Supervision: The TLV809K33DBZR monitors the supply voltage (VDD) and keeps your system stable by providing a reset signal to the host processor whenever VDD drops below the factory-programmed threshold of 3.3V.
• Low Power Consumption: With a quiescent current of just 10 μA (typical), this voltage supervisor is incredibly power-efficient, making it ideal for portable and battery-operated applications.
• Programmable Delay Time: It offers an adjustable delay time after the voltage level returns above the threshold before the reset signal is deasserted, allowing for system stabilization.
• High Accuracy: The reset threshold voltage is accurate to within ±1.5%, ensuring dependable monitoring and protection for sensitive electronics.
• Small Form Factor: Packaged in a compact 3-pin SOT-23 (DBZ) package, the TLV809K33DBZR is designed for space-constrained applications.
• Temperature Range: It operates over a wide temperature range of –40°C to +85°C, suitable for industrial and commercial environments.

Applications

The TLV809K33DBZR is versatile and can be used in a variety of applications, including:

• Microprocessor, microcontroller, or DSP systems
• Portable and battery-powered equipment
• Industrial controls
• Smart home devices
• Consumer electronics
• Networking equipment

With its precise voltage monitoring and low power consumption, the TLV809K33DBZR from Texas Instruments is an excellent choice for designers looking to enhance the reliability and performance of their electronic systems.
