Product Overview: Texas Instruments TLC7703ID

The Texas Instruments TLC7703ID is a precision supply voltage supervisor designed to monitor power supplies in digital systems. It provides the necessary circuitry to tailor the reset function to the specific requirements of your microprocessor (µP) or digital system. Ensuring a reliable operation and preventing potential damage due to unpredictable events such as power surges, the TLC7703ID is an essential component for maintaining system integrity.

Key Features

• Voltage Supervision: The TLC7703ID offers a precise 3.3 V detection voltage, making it suitable for supervising 3.3 V power supplies and ensuring that the system voltage remains within acceptable thresholds.
• Programmable Reset Delay: It includes an external delay timing capacitor that allows users to program the reset signal's duration to match specific system requirements.
• Low Power Consumption: With a typical supply current of only 12 µA, this voltage supervisor is an energy-efficient solution that minimizes the power draw on the system.
• Temperature Range: The device operates over a wide temperature range from -40°C to 85°C, ensuring reliable performance in various environmental conditions.
• Output Driver: The open-drain RESET output can sink a significant current, allowing direct connection to the reset pin of the µP, and is capable of interfacing with both TTL and CMOS logic.
• Push-Pull RESET: The TLC7703ID variant provides a push-pull RESET output that remains operational even during power-down conditions.

Applications

The TLC7703ID is versatile and can be used in a variety of applications where precise voltage supervision is critical. It is particularly useful in systems that require a controlled reset operation upon power-up or brownout conditions. Typical applications include:

• Microprocessor, microcontroller, or DSP systems
• Portable/battery-powered equipment
• Intelligent instruments
