Overview of Texas Instruments TLV809EA22DBZR

The Texas Instruments TLV809EA22DBZR is a specialized microprocessor supervisory circuit that provides crucial monitoring functionality for embedded systems. Designed to maintain the integrity of system operations, this device monitors the supply voltage of a microprocessor (µP), microcontroller (MCU), or other digital systems, ensuring that the system operates optimally within its voltage thresholds.

Key Features

• Voltage Monitoring: The TLV809EA22DBZR offers precise monitoring of a fixed voltage threshold of 2.2V, which is vital for systems that require a stable power supply to function correctly.
• Reset Output: In the event of a voltage drop below the threshold, the device generates a reset signal, which is maintained for a minimum of 140ms after the supply voltage has risen above the reset voltage threshold. This helps to ensure that the system has sufficient time to return to a stable state before resuming operation.
• Low Power Consumption: With a low quiescent current, the device is suitable for power-sensitive applications, making it an efficient choice for battery-operated devices.
• Small Form Factor: The TLV809EA22DBZR comes in a compact SOT-23 package, which is ideal for space-constrained applications.

Applications

The TLV809EA22DBZR is versatile and can be used in a variety of applications where reliable voltage monitoring is crucial. These include:

• Portable and battery-powered electronics
• Microprocessor/microcontroller systems
• Industrial equipment
• Automotive systems
• Smart appliances
