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