ON Semiconductor CAT811RTBI-GT3 Voltage Supervisor

The CAT811RTBI-GT3 from ON Semiconductor is a high-performance microprocessor supervisory circuit designed to maintain system integrity during power failures or unexpected power-down events. This compact and efficient component is an essential addition to a wide range of electronic applications, including computers, controllers, and portable electronic devices, where precise voltage monitoring is critical for reliable operation.

At the heart of the CAT811RTBI-GT3 is a precision voltage reference and comparator circuit that monitors the VCC supply voltage and maintains a reset signal until the VCC voltage exceeds the factory-programmed threshold. The reset signal is kept active for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset during power-up, power-down, or brown-out conditions. This feature is crucial for systems that require a stable and reliable startup.

This voltage supervisor operates over a wide supply voltage range, typically from 1.0V to 5.5V, making it versatile for various applications. The low supply current of typically 5µA ensures minimal power consumption, contributing to the energy efficiency of the overall system. The device comes in a compact 5-pin SOT-23 package, which is ideal for space-constrained applications.

The CAT811RTBI-GT3 also includes additional features such as a manual reset input, which allows the system to be reset via an external push-button or logic signal. This manual reset capability provides designers with greater flexibility and control over the reset functionality of their systems.

ON Semiconductor's commitment to quality and reliability is evident in the CAT811RTBI-GT3, which is designed and manufactured to meet the stringent requirements of the industrial and consumer electronics markets. With its precision voltage monitoring and low power consumption, the CAT811RTBI-GT3 is a smart choice for designers looking to enhance the safety and robustness of their electronic systems.

Overall, the CAT811RTBI-GT3 is a testament to ON Semiconductor's expertise in power management and supervisory circuits, offering both performance and peace of mind for complex electronic systems.
