input for voltages up to 5.5V. Operates as a shunt regulator  
for supply voltages greater than 5.7V and should have a  
MR (LTC2918 only): Manual Reset Input (Active Low). A low  
level on the MR input causes the part to issue a reset, which  
is released one reset timeout after the input goes high. The pin  
has an internal 100k pull-up to V , and thus may interface  
directly to a momentary pushbutton. Leave open if unused.

current to no greater than 5mA. When used without a cur-  
rent-limiting resistor, pin voltage must not exceed 5.7V.  
RST: Open Drain RST Output. Asserts low when VM is  
belowthethresholdselectedbySEL1,SEL2andTOLinput  
pins. Held low for an adjustable timeout after VM input is  
above threshold.  
VM:VoltageMonitorInputtoRSTcomparator.SEL1,SEL2  
and TOL inputs select the exact threshold that asserts the  
RST output.  
WDI: Watchdog Input. This pin must be driven to change  
state within a time less than the watchdog upper bound-  
ary time, or RST will be asserted low. On the LTC2917-B,  
LTC2918-B, the period must also be greater than the  
watchdog lower boundary time, and only falling edges  
are considered. Tie WT and WDI to GND to disable the  
watchdog timer.  
RT: Reset Timeout Control Pin. Attach an external capacitor
