Overview of Texas Instruments TL7705 Supply Voltage Supervisor
The Texas Instruments TL7705 is a dedicated supply voltage supervisor designed to provide reliable reset control for microprocessors (µP) and other digital systems. It ensures that the power supply voltage is stable and within acceptable limits before allowing the digital system to operate, thereby preventing potential damage due to power supply fluctuations or anomalies.
Key Features
- Supply Voltage Monitoring: The TL7705 continuously monitors the supply voltage of a microprocessor or digital system, ensuring that the supply remains above a predetermined threshold before the system is allowed to start or continue operation.
- Programmable Reset Delay: It offers an adjustable delay time which is set by an external capacitor. This feature allows designers to customize the reset timing to match specific system requirements.
- High Accuracy: This voltage supervisor offers high precision in monitoring voltage levels, contributing to the overall reliability of the system it is protecting.
- Low Power Consumption: The device is designed for low power consumption, making it suitable for battery-operated systems where power efficiency is critical.
- Wide Operating Temperature Range: The TL7705 is capable of operating over a wide temperature range, making it suitable for industrial applications subjected to harsh environmental conditions.
