CAT809RTBI-T3 Description
CAT809RTBI-T3 Description
The CAT809RTBI-T3 is a single-channel voltage supervisor IC designed for power management applications. Manufactured by onsemi, this device is housed in a compact SOT23-3 package, making it suitable for space-constrained designs. The CAT809RTBI-T3 monitors a single voltage rail with a threshold of 2.63V, ensuring reliable system operation by providing a reset signal when the monitored voltage falls below this threshold. The reset signal is active low, and the device features a minimum reset timeout of 140ms, which is crucial for ensuring proper system reset and stability. The CAT809RTBI-T3 is available in a surface-mount package, specifically in tape and reel format (TR), facilitating automated assembly processes. Despite its obsolescence, the CAT809RTBI-T3 remains a viable option for legacy designs and applications that require a dependable voltage monitoring solution. It is classified under ECCN EAR99 and is unaffected by REACH regulations, ensuring compliance with international standards.
