ON Semiconductor CAT812RTBI-T3 Supervisory Circuit

The CAT812RTBI-T3 is a highly reliable supervisory circuit designed by ON Semiconductor, a leader in energy-efficient innovations. This compact component is essential for monitoring the power supply voltage levels in microprocessor systems, ensuring your electronics maintain optimal performance and protection.

Featuring a precision voltage monitor, the CAT812RTBI-T3 provides a fixed threshold voltage of 4.38V, making it suitable for 5V-powered applications. Its primary function is to assert a reset signal whenever the V<sub>CC supply voltage falls below this threshold, effectively safeguarding the system against brown-out conditions and power failures. The reset signal maintains its state for a minimum of 140ms after V<sub>CC has risen above the reset threshold, ensuring system stability.

This supervisory circuit is particularly noted for its low power consumption, drawing a minimal quiescent current, which is a critical feature for battery-powered devices. The CAT812RTBI-T3 is designed to operate over a wide temperature range of -40°C to +85°C, making it versatile for various industrial applications.

The CAT812RTBI-T3 is available in a 3-pin SOT-23 package, which is popular for surface-mounted technology due to its small footprint. This package allows for efficient space utilization on printed circuit boards, an important consideration for modern electronic devices where space is at a premium.

ON Semiconductor's commitment to quality ensures that the CAT812RTBI-T3 meets stringent industry standards for reliability and performance. It is designed for use in microprocessor-based systems, such as computers, controllers, and intelligent instruments, where precise voltage monitoring is crucial.

In summary, the CAT812RTBI-T3 supervisory circuit from ON Semiconductor is an indispensable component for any system requiring accurate voltage monitoring and reset capabilities. Its low power consumption, small package size, and wide operating temperature range make it an excellent choice for a variety of applications where efficiency and reliability are paramount.
