CAT859FTBI-GT3

CAT859FTBI-GT3 Description

The CAT859FTBI-GT3 is a 1-channel voltage supervisor IC designed for power management applications. Manufactured by onsemi, this device is part of the Power Management (PMIC) category and is housed in a SOT23-3 package. This IC is designed to monitor a single voltage and provide a reset signal when the monitored voltage falls below a predefined threshold. The CAT859FTBI-GT3 features a voltage threshold of 4.2V and a minimum reset timeout of 140ms. It is suitable for surface mount applications and is available in a tape and reel (TR) package format. The device has a moisture sensitivity level (MSL) of 1, indicating it is unaffected by moisture and can be stored without time constraints. The CAT859FTBI-GT3 is classified under the ECCN EAR99 and is REACH unaffected, ensuring compliance with international regulations. Although the product status is marked as obsolete, it remains a reliable choice for legacy systems and specific applications where its unique features are required.
