TLV809I50DBZT

The TLV809I50DBZT is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor supply voltages and provide a reset signal when the voltage falls below a specified threshold. Here’s a detailed description of its features and specifications:

Key Features:

1. Voltage Monitoring: The TLV809 monitors supply voltages and ensures that the system operates within safe voltage levels. It is particularly useful in microcontroller applications where a stable voltage is critical for reliable operation.

2. Reset Threshold: The device has a fixed reset threshold voltage of 5.0V. This means that it will assert a reset signal when the supply voltage drops below this level, helping to prevent erratic behavior in digital circuits.

3. Active-Low Reset Output: The reset output is active-low, meaning that it goes low (0V) when a reset condition is detected. This output can be connected to the reset pin of a microcontroller or other digital devices.

4. Reset Timeout: The TLV809 features a built-in reset timeout period, which ensures that the reset signal remains asserted for a specified duration after the supply voltage has returned to a safe level. This allows time for the system to stabilize before resuming normal operation.

5. Low Quiescent Current: The device is designed to operate with low quiescent current, making it suitable for battery-powered applications where power efficiency is crucial.

6. Wide Operating Voltage Range: The TLV809 can operate over a wide range of supply voltages, typically from 1.0V to 6.0V, making it versatile for various applications.

7. Temperature Range: The device is rated for operation over an extended temperature range, typically from -40°C to +125°C, ensuring reliability in harsh environments.

8. Small Package Size: The TLV809I50DBZT is available in a compact SOT-23 package, which is ideal for space-constrained applications.

Applications:

• Microcontroller and microprocessor reset circuits
• Power management systems
• Automotive electronics
• Industrial control systems
