Overview of ON Semiconductor CAT809MTBI-GT3

The ON Semiconductor CAT809MTBI-GT3 is a high-performance, precision microprocessor (μP) supervisory circuit designed to monitor system voltage levels and provide a reliable reset signal to the μP during power-up, power-down, or brown-out conditions. This component ensures that the μP resets properly during a system fault, such as a power interruption, thereby enhancing system reliability.

Key Features

• Voltage Monitoring: The device actively monitors the VCC supply voltage and maintains a reset signal to the μP until it stabilizes above the minimum VCC threshold.
• Reset Timeout: It features a built-in delay to ensure the system has sufficient time to stabilize before the μP starts its operation. The reset signal is maintained for a period after VCC has risen above the reset threshold level.
• Low Power Consumption: Designed for battery-powered and portable applications, the CAT809MTBI-GT3 boasts a low power consumption, helping to extend battery life and reduce energy costs.
• High Accuracy: This supervisory circuit provides a high degree of accuracy in monitoring the system voltage, ensuring precise reset threshold levels.
• Temperature Range: The device operates over a wide temperature range, making it suitable for various industrial and consumer applications.
• Compact Package: The CAT809MTBI-GT3 comes in a compact 3-lead SOT-23 package, which is ideal for space-constrained applications.

Applications

The ON Semiconductor CAT809MTBI-GT3 is versatile and can be used in a wide array of applications, including:

• Computers and computer peripherals
• Embedded systems
• Portable and battery-powered devices
• Intelligent instruments
• Industrial controllers

Conclusion

With its precision voltage monitoring and low power consumption, the ON Semiconductor CAT809MTBI-GT3 is an essential component for ensuring the reliability and stability of microprocessor systems. Its small form factor and wide temperature range make it an excellent choice for designers looking for a reset supervisory circuit that can be easily integrated into a variety of electronic products.
