CAT811MTBI-T3

CAT811MTBI-T3 Description

The CAT811MTBI-T3 is a high-performance power management integrated circuit (PMIC) designed for voltage monitoring applications. Manufactured by onsemi, this IC supervisor features a single-channel voltage monitor with a threshold voltage of 4.38V. It is packaged in a Surface Mount SOT143 form factor, making it suitable for compact and space-constrained designs. The device is available in a Tape & Reel (TR) package, facilitating efficient manufacturing processes.

CAT811MTBI-T3 Features

• Single Voltage Monitoring: The CAT811MTBI-T3 is designed to monitor a single voltage rail, ensuring that the system operates within specified voltage levels. This feature is particularly useful in applications where a single critical power supply needs to be monitored.
• Active Low Reset: The reset output is active low, providing a reliable and straightforward reset signal to the system. This ensures that the system can be safely reset when the monitored voltage falls below the threshold.
• 140ms Minimum Reset Timeout: The device offers a minimum reset timeout of 140 milliseconds, providing sufficient time for the system to stabilize after a reset event. This feature ensures that transient voltage drops do not cause unintended resets.
• Surface Mount Technology: The Surface Mount package type allows for easy integration into modern PCB designs, enhancing reliability and reducing the overall footprint of the design.
• Moisture Sensitivity Level (MSL) 1: The CAT811MTBI-T3 is rated for MSL 1, meaning it is suitable for unlimited exposure to ambient conditions, making it ideal for a wide range of manufacturing environments.
• Compliance and Standards: The device is REACH unaffected and classified under ECCN EAR99, ensuring compliance with international regulations and standards.
