CAT1640LI-45-G Description

The CAT1640LI-45-G is a single-channel supervisory IC designed for power management applications. Manufactured by onsemi, this device is part of the Power Management (PMIC) category and is housed in an 8DIP package. It features a voltage threshold of 4.5V and is capable of monitoring a single voltage level. The IC operates with an open drain or open collector output and has an active low reset function with a minimum reset timeout of 130ms. The CAT1640LI-45-G is designed for through-hole mounting and is packaged in a tube. It has a moisture sensitivity level (MSL) of 1, indicating it is unaffected by moisture and can be stored without limitations. The product is classified under HTSUS code 8542.39.0001 and falls under the ECCN classification EAR99. It is important to note that the CAT1640LI-45-G is currently in an obsolete product status, and its DigiKey programmability has not been verified. The REACH status of the product is unaffected, ensuring compliance with environmental regulations.
