TL7705ACDRE4

The TL7705ACDRE4 is a precision voltage supervisor and reset circuit manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold.

Key Features:

1. Voltage Monitoring: The TL7705ACDRE4 monitors the supply voltage and ensures that the voltage remains within a specified range. If the voltage drops below the preset threshold, the device generates a reset signal.

2. Reset Output: The reset output is active low, meaning that it goes low when the monitored voltage is below the threshold. This output can be connected to the reset pin of a microcontroller or other digital logic devices to ensure they operate correctly.

3. Adjustable Threshold: The device allows for an adjustable reset threshold, which can be set using external resistors. This flexibility makes it suitable for various applications with different voltage requirements.

4. Low Power Consumption: The TL7705ACDRE4 is designed for low power operation, making it ideal for battery-powered devices and applications where power efficiency is critical.

5. Temperature Range: The device operates over a wide temperature range, typically from -40°C to +125°C, ensuring reliability in various environmental conditions.

6. Package Type: The TL7705ACDRE4 is available in a small, surface-mount package (SOT-23), which is suitable for compact designs and helps save board space.

7. Applications: Common applications include microcontroller reset circuits, power supply monitoring, automotive electronics, and any system requiring reliable voltage supervision.

Electrical Characteristics:

• Supply Voltage Range: The device typically operates within a range of 2.5V to 15V.
• Reset Threshold Voltage: The reset threshold can be set to various levels, commonly around 4.63V, but can be adjusted based on the application needs.
• Reset Timeout: The reset signal remains active for a specified timeout period after the voltage returns to normal levels, ensuring that the system has stabilized before resuming operation.

Conclusion:

The TL7705ACDRE4 from Texas Instruments is a versatile and reliable voltage supervisor that plays a critical role in ensuring the proper operation of electronic systems by providing timely reset signals in response to voltage fluctuations. Its combination of low power consumption, adjustable thresholds, and robust performance makes it a popular choice in a wide range of electronic applications.
