OPERATION - POWER MONITOR
The DS1810 provides the function of detecting out-of-tolerance power supply conditions and warning a
processor-based system of impending power failure. When V
signal is asserted. On power-up,
reached the selected tolerance. This allows the power supply and microprocessor to stabilize before
is released.

OUTPUT VALID CONDITIONS
All versions of the DS1810 can maintain a valid output as long as V

volts on an input. To sink current below 1.2 volts, a resistor can be connected from
Figure 3). This arrangement will maintain a valid value on the
volts. During both power-up and -down this arrangement will draw current when
A value of about 100 kV should be adequate to maintain a valid condition.
