® SP706P/R/S/T, SP708R/S/T +3.0V/+3.3V Low Power Microprocessor Supervisory Circuits s Precision Low Voltage Monitor: SP706P/R and SP708R at +2.63V SP706S and SP708S at +2.93V SP706T and SP708T at +3.08V s RESET Pulse Width - 200ms s Independent Watchdog Timer - 1.6 sec Timeout (SP706P/S/R/T) s 40µA Maximum Supply Current s Debounced TTL/CMOS Manual-Reset Input s RESET Asserted Down to VCC = 1V s RESET Output: SP706P Active-High SP706R/S/T Active-Low SP708R/S/T Both Active High + Active Low s WDI Can Be Left Floating, Disabling the Watchdog Function DESCRIPTION The SP706P/S/R/T, SP708R/S/T series is a family of microprocessor (µP) supervisory circuits that integrate myriad components involved in discrete solutions which monitor power-supply and battery, in µP, and digital systems. The SP706P/S/R/T, SP708R/S/T series will significantly improve system reliability and operational efficiency when compared to results obtained with discrete components. The features of the SP706P/S/R/T, SP708R/S/T series include a watchdog timer, a µP reset, a Power Fail Comparator, and a manual-reset input. The SP706P/ S/R/T, SP708R/S/T series is ideal for +3.0V or +3.3V applications in automotive systems, computers, controllers, and intelligent instruments. The SP706P/S/R/T, 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 demanded.
