The LTC1235 provides complete power supply monitoring  
and battery control functions for microprocessor reset,  
battery backup, RAM write protection, power failure warn-  
ing and watchdog timing. The LTC1235 has all the LTC695  
features plus conditional battery backup and external reset  
control. When an out-of-tolerance power supply condition  
occurs, the reset outputs are forced to active states and the  
Chip Enable output write-protects external memory. The  
RESET output is guaranteed to remain logic low with VCC as  
lowas1V.Externalresetcontrolisprovidedbyadebounced  
push-button reset input.

The LTC1235 powers the active CMOS RAMs with a charge  
pumped NMOS power switch to achieve low dropout and  
low supply current. When primary power is lost, auxiliary  
power, connected to the battery input pin, provides backup  
power to the RAMs. The LTC1235 can be programmed by  
a µP signal to either back up the RAMs or not. This extends  
the battery life in situations where RAM data need not  
always be saved when power goes down.

For an early warning of impending power failure, the  
LTC1235 provides an internal comparator with a user-  
defined threshold. An internal watchdog timer is also avail-  
able, which forces the reset pins to active states when the  
watchdog input is not toggled prior to the time-out period.
