ON Semiconductor CAT809JTBI-T3 Supervisory Circuit

The CAT809JTBI-T3 is a highly reliable supervisory circuit designed and manufactured by ON Semiconductor, a leading provider of semiconductor-based solutions. This precision device is engineered to monitor power supply and system health, ensuring that electronic products operate within their specified voltage range. It is a crucial component for enhancing system reliability and preventing damage caused by irregular power supply conditions.

The CAT809 series offers a variety of voltage threshold options, and the CAT809JTBI-T3 variant specifically provides a nominal threshold voltage of 4.38V, making it suitable for systems that operate around this voltage level. This voltage monitor is designed to assert a reset signal whenever the VCC supply voltage falls below the factory-programmed threshold. The reset signal remains asserted for a period of time after VCC has risen above the threshold, ensuring the system has stabilized before normal operation resumes. This timeout period is typically 140ms, which provides ample time for system recovery.

The device comes in a compact, 3-pin SOT-23 package, which is ideal for space-constrained applications. Its low power consumption makes it an excellent choice for portable and battery-powered devices. The CAT809JTBI-T3 operates over a wide temperature range of -40°C to +85°C, ensuring reliability and performance under various environmental conditions.

Key features of the CAT809JTBI-T3 include:

• Precision monitoring of 4.38V power supplies.
• Low power consumption for enhanced battery life.
• 140ms minimum reset timeout period.
• Wide operating temperature range.
• Compact SOT-23 package.

The CAT809JTBI-T3 is an essential component for applications requiring precise voltage supervision, such as microcontrollers, computers, embedded systems, and other electronic devices. Its robust design and ON Semiconductor's commitment to quality make it a trusted solution for safeguarding your critical systems against power supply anomalies.
