The SP705-708/813L series is a family of microprocessor (µA) supervisory circuits that integrate myriad components involved in discrete solutions which monitor power-supply and battery in mP and digital systems.

The SP705-708/813L 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 SP705-708/813L 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:
  • RESET pulse width - 200ms
  • Independent watchdog timer - 1.6s
  • Timeout (SP705/706/813L/813M)
  • 60mA maximum supply current
  • Debounced TTL/CMOS manual reset input
