DESCRIPTION (Continued)  
PIN CONFIGURATION  
The Watchdog Timer provides an independent protec-  
tion mechanism for microcontrollers. When the micro-  
controller fails to restart a timer within a selectable  
time out interval, the device activates the WDO signal.  
The user selects the interval from three preset values.  
Once selected, the interval does not change, even  
after cycling the power.

V2FAIL  
V2 Voltage Fail Output. This open drain output goes LOW when V2MON is less than VTRIP2 and  
goes HIGH when V2MON exceeds VTRIP2. There is no power-up reset delay circuitry on this pin.

V2MON  
V2 Voltage Monitor Input. When the V2MON input is less than the VTRIP2 voltage, V2FAIL goes  
LOW. This input can monitor an unregulated power supply with an external resistor divider or can  
monitor a second power supply with no external components. Connect V2MON to VSS or VCC  
when not used.
