SP708S Datasheet | MaxLinear

Description The SP706R / SP706S / SP706T and SP708S / SP708T series is a family of microprocessor (µP) supervisory circuits that integrate a myriad of ponents involved in discrete solutions which monitor power-supplies and batteries in µP and digital systems. The SP706R / SP706S / SP706T and SP708S / SP708T series will significantly improve system reliability and operational efficiency when pared to solutions using discrete ponents. The features of the SP706R / SP706S / SP706T and SP708S / SP708T series include a watchdog timer, a µP reset, a power fail parator, and a manualreset input. The SP706R / SP706S / SP706T and SP708S / SP708T series is ideal for 3.0V or 3.3V applications in automotive systems, puters, controllers and intelligent instruments. The SP706R / SP706S / SP706T and SP708S / SP708T series is an ideal solution for systems in which critical monitoring of the power supply to the µP and related digital ponents is demanded.
