This is the part you reach for when a system needs to retain calibration data, transaction logs, or timekeeping through a brownout or brief power loss — think industrial controllers, metering equipment, or security panels. The operating temperature range of -40°C to 85°C covers the industrial temperature grade, so this supervisor is rated for outdoor telecom cabinets, unheated factory floors, and engine-bay-adjacent enclosures where the ambient can swing well outside commercial limits. ## 140ms reset timeout — why it matters The 140ms minimum reset timeout holds the reset line low after the supply returns above the threshold. That window lets the oscillator start and the power rails settle before the processor begins fetching instructions. ## Active production — no LTB risk The MAX808LEPA is listed as Active in production status. For a BOM line that needs a through-hole supervisor with battery backup, this part is a stable choice for new builds and ongoing production — no urgent need to qualify a second source for lifecycle reasons. ## RoHS note — verify your compliance requirements This part is marked RoHS non-compliant. If your assembly line or end-market requires RoHS exemption-free compliance (e.g., EU RoHS for consumer goods, WEEE directives), the MAX808LEPA will not pass incoming inspection. For RoHS-required builds, look at the lead-free variant in the same family — the suffix differs. For military, aerospace, or high-reliability applications that explicitly exempt leaded solder, the non-compliant status is often acceptable or even preferred.","metaTitle":"MAX808LEPA Battery Backup Circuit, 4.675V Threshold","metaDescription":"MAX808LEPA is an active MPU supervisor IC with battery backup, 4.675V threshold, 140ms reset timeout, push-pull output, through-hole 8-DIP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Through Hole","Reset Timeout":"140ms Minimum","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.675V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-PDIP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.81","stockQuantity":0,"priceTiers":[{"qty":52,"price":"$5.81000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2f77645567050eaa0f132dc9c3bcaf45.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for MAX808LEPA?","answer":"The reset timeout is a minimum of 140ms.
