The SP705-708 / SP813L series is a family of microprocessor (μP) supervisory circuits that integrate myriad components involved in discrete solutions which monitor power-supply and battery in mP and digital systems.
 
The SP705-708 / SP813L series will significantly improve system reliability and operational efficiency when compared to solutions obtained with discrete components. The features of the SP705-708/813L series include a watchdog timer, a μP reset, a Power Fail Comparator, and a manual-reset input.
 
The SP705-708 / SP813L series is ideal for applications in automotive systems, computers, controllers, and intelligent instruments. The SP705-708/813L series is an ideal solution for systems in which critical monitoring of the power supply to the μP and related digital components is demanded.

  • Precision voltage monitor:
    • SP705/SP707/SP813L at 4.65V
    • SP706/SP708/SP813M at 4.40V
  • RESET pulse width - 200ms
  • Independent watchdog timer - 1.6s
  • Timeout (SP705/706/813L/813M)
  • 60mA maximum supply current
  • Debounced TTL/CMOS manual reset input
  • RESET asserted down to VCC = 1V
  • Voltage monitor for power failure or low battery warning
  • Available in 8-pin PDIP, NSOIC, and uSOIC packages
  • Pin compatible enhancement to industry standard 705-708/813L series
  • Functionally compatible to industry standard 1232 series

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.
