The SP706R/S/T and SP708R/S/T series is a family of microprocessor (µP) supervisory circuits that integrate the myriad components required by discrete solutions which monitor power-supplies and batteries in µP and digital systems.

The SP706R/S/T and SP708R/S/T series significantly improve system reliability and operational efficiency when compared to solutions using discrete components. The features of the SP706R/S/T and SP708R/S/T series include a watchdog timer, a µP reset, a power fail comparator and a manual-reset input.

The SP706R/S/T and SP708R/S/T series is ideal for 3.0V or 3.3V applications in automotive systems, computers, controllers, and intelligent instruments. The SP706R/S/T and SP708R/S/T series is an ideal solution for systems in which critical monitoring of the power supply to the µP and related digital components is required.

Distribution Date Description File
07/17/2023 In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023.
