Overview of Texas Instruments TLV809J25DBZT

The TLV809J25DBZT is a sophisticated voltage supervisor component designed by Texas Instruments to ensure reliable system performance through precise monitoring of power supplies. This compact, fixed-sense threshold voltage supervisor is engineered to maintain system integrity by providing a reset signal to microprocessors (μPs), microcontrollers (MCUs), and other digital systems upon detecting a voltage drop below a predetermined threshold.

Key Features

• Fixed Voltage Threshold: The TLV809J25DBZT comes with a preset threshold voltage of 2.5V, which is ideal for monitoring 2.5V power rails.
• Low Power Consumption: This device is optimized for battery-powered applications, with a low quiescent current that extends battery life.
• Manual Reset Input: It includes a manual reset (MR) input that allows the user to trigger a reset pulse manually.
• High Accuracy: The reset threshold voltage is highly accurate, ensuring precise monitoring and reliable operation of the connected system.
• Fast Response Time: The device features a fast response time to voltage changes, quickly asserting the reset signal when necessary.
• Open-Drain RESET Output: The reset output is of the open-drain type, which allows for wired-OR connections and provides flexibility in interfacing with different logic levels.

Applications

The TLV809J25DBZT is versatile and can be used in a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Microprocessor, Microcontroller, or DSP Systems
• Industrial Equipment
• Data Storage Systems
• Consumer Electronics
