ON Semiconductor CAT812RTBI-GT3 Voltage Supervisor IC

The ON Semiconductor CAT812RTBI-GT3 is a highly reliable, precision voltage supervisor device designed to maintain system integrity by monitoring the supply voltage of digital systems. This compact component is an essential part of many electronic applications, ensuring that microprocessors, microcontrollers, and other digital systems reset properly during a power loss or drop in voltage.

Featuring a 4.38V threshold voltage, the CAT812RTBI-GT3 provides a robust solution for systems that require a precise monitoring voltage level. Its tight precision of ±1.5% ensures accurate voltage detection, which is critical for sensitive electronics that can be disrupted by even small deviations in power supply.

The device comes in a small, 3-pin SOT-23 package, making it an ideal choice for space-constrained applications. Despite its compact size, it does not compromise on performance, offering low power consumption and a wide operating temperature range from -40°C to +85°C, which allows for deployment in various environments and conditions.

One of the key features of the CAT812RTBI-GT3 is its active-low, push-pull reset output. This output type provides a quick and decisive signal that can directly interface with other components in the system without the need for additional buffering. The active-low configuration ensures that the reset signal is asserted (logic low) whenever the monitored voltage falls below the threshold, providing an immediate response to voltage dips.

Additionally, the device has a built-in delay time of 140ms (minimum), which prevents false triggering due to transient voltage fluctuations. This delay ensures that the system only resets when necessary, avoiding unnecessary interruptions to system operation.

With its high accuracy, low power consumption, and compact form factor, the CAT812RTBI-GT3 from ON Semiconductor is an excellent choice for designers looking to enhance the reliability and stability of their digital systems. Its ease of integration into existing designs, along with its robust feature set, makes it a versatile component for a wide range of applications, from consumer electronics to industrial control systems.

Overall, the CAT812RTBI-GT3 is a testament to ON Semiconductor's commitment to providing high-quality, reliable components for the electronics industry.
