ON Semiconductor CAT811LTBI-T3 Voltage Supervisor IC

The ON Semiconductor CAT811LTBI-T3 is a precision voltage supervisor device designed to enable systems to monitor their own supply voltages. This is essential for applications that require a high level of reliability and operational stability. The CAT811LTBI-T3 is part of ON Semiconductor's portfolio of microprocessor supervisory circuits, providing a robust solution for monitoring power supply conditions in digital systems.

This compact IC is specifically tailored to maintain system integrity by monitoring the VCC supply voltage and asserting a reset signal whenever VCC drops below a preset threshold. The reset signal remains asserted until the supply voltage returns to proper operating levels and a preset delay time has elapsed. This ensures that the system has adequate time to return to a stable state before resuming operation.

The CAT811LTBI-T3 offers several key features that make it a versatile and reliable choice for power management tasks:

• Precision Monitoring: With tight threshold accuracy, the device ensures that voltage levels are monitored with precision, minimizing the risk of improper system resets.
• Low Power Consumption: The low power draw of the CAT811LTBI-T3 helps to conserve energy, making it suitable for power-sensitive applications.
• Programmable Delay: The reset timeout period can be programmed according to system requirements, allowing for flexibility in different use cases.
• Manual Reset Input: A manual reset input provides an additional layer of control, allowing for system resets to be initiated as needed.
• Temperature Range: The device operates over a wide temperature range, ensuring reliable performance under varying environmental conditions.

The CAT811LTBI-T3 is available in a 5-lead SOT-23 package, making it suitable for space-constrained applications. Its small footprint does not compromise on functionality, offering system designers a compact solution without sacrificing performance.

Whether used in computers, controllers, portable devices, or other digital systems, the CAT811LTBI-T3 from ON Semiconductor provides an effective means of safeguarding system integrity through accurate and reliable voltage supervision.
