OPERATION
Power Monitor
The DS1836 provides the functions of detecting out-of-tolerance conditions on a 3.3V or 5V power
supply and warning a processor-based system of impending power failure. When V CC is detected as out of
tolerance the RST will be forced active. When V CC returns to a valid state the RST will remain active for
about 350ms and then return to an inactive state until the next V CC out-of-tolerance condition.
On power-up reset is kept active for approximately 350ms after the power supply input has reached the
selected tolerance. This allows the power supply and system power to stabilize before RST is released.
Power Switch (DS1836A & B)
The DS1836 switches the V OUT output between V CC and V BAT . On the initial power-up, V OUT draws
current from the V BAT input until V CC exceeds 3.9V. When V CC exceeds 3.9V V OUT switches from V BAT
to V CC and will not switch back to V BAT until V CC drops below 3.8V. When V CC is below 3.8V, power
will be drawn from the supply with the highest voltage: either V CC or V BAT .
Power Switch (DS1836C & D)
The DS1836 switches the V OUT output between V CC and V BAT . On the initial power up, V OUT draws
current from the V BAT input until V CC exceeds 2.8V. When V CC exceeds 2.8V V OUT switches from V BAT
to V CC and will not switch back to V BAT until V CC drops below 2.6V. When V CC is below 2.6V, power
will be drawn from the supply with the highest voltage either V CC or V BAT .
