Overview of Texas Instruments TLC7733ID Voltage Supervisor

The Texas Instruments TLC7733ID is a precision supply voltage supervisor designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. This device helps to ensure that the system boots up in a predictable state every time it is powered on or when there is a drop in the supply voltage below a designated threshold, known as the reset threshold voltage.

Key Features

• Programmable Reset Delay: The TLC7733ID comes with an externally programmable delay time for the reset signal, providing flexibility to suit various system requirements.
• Low Supply Current: With a typical supply current of 15 µA, this voltage supervisor is an energy-efficient solution for power-conscious applications.
• High Accuracy: The device features a precision voltage sensor, which is critical for reliable operation of microprocessors and other digital systems.
• Wide Operating Range: The TLC7733ID operates over a range of 1.1 V to 5.5 V, accommodating a variety of digital circuits and systems.
• Active-Low Reset: It provides an active-low reset signal, which is a common requirement for interfacing with a multitude of microprocessors and digital ICs.

Applications

The TLC7733ID is suitable for a wide range of applications that require voltage supervision, including:

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