DESCRIPTION
The SP690T/S/R, SP802T/S/R, SP804T/S/R and SP805T/S/R devices are a family of microprocessor (µP) supervisory circuits that integrate a myriad of components involved in discrete solutions to monitor power-supply and battery-control functions in µP and digital systems. The series will significantly improve system reliability and operational efficiency when compared to discrete solutions.
