The LTC690 family powers the active CMOS RAMs with a  
charge pumped NMOS power switch to achieve low drop-  
out and low supply current. When primary power is lost,  
auxiliarypower,connectedtothebatteryinputpin,powers  
the RAMs in standby through an efficient PMOS switch.

■
For an early warning of impending power failure, the  
LTC690 family provides an internal comparator with a  
user-definedthreshold. Aninternalwatchdogtimeris also  
available, which forces the reset pins to active states when  
thewatchdoginputis nottoggledpriortoapresettime-out
