DS1813
OPERATION—POWER MONITOR
The DS1813 provides the functions of detecting out-of-tolerance power-supply conditions and warning a
processor-based system of impending power failure. When V CC is detected as out-of-tolerance, the RST
signal is asserted. On power-up, RST is kept active for approximately 150ms after the power supply has
reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RST
is released.
OPERATION—PUSHBUTTON RESET
The DS1813 provides for a pushbutton switch for manual reset control. When the DS1813 is not in a reset
cycle, a pushbutton reset can be generated by pulling the RST pin low for at least 1μs. When the
pushbutton is held low, the RST is forced active low and will remain active low for about 150ms after the
pushbutton is released. See Figure 2 for an application example and Figure 3 for the timing diagram.
