DS1233
OPERATION — PUSHBUTTON RESET
The DS1233 provides for a pushbutton switch to be connected to the
output pin. When the DS1233
RST
is not in a reset cycle, it continuously monitors the
signal for a low going edge. If an edge is
RST
detected, the DS1233 will debounce the switch by pulling the
line low. After the internal timer has
RST
expired, the DS1233 will continue to monitor the
line. If the line is still low, the DS1233 will
RST
continue to monitor the line looking for a rising edge. Upon detecting a release, the DS1233 will force the
line low and hold it low for 350ms.
RST
NOTE:
For proper operation with an external pushbutton, a capacitor between 100pF and 0.01mF must be
connected between
and ground. In applications where additional reset current is required, a
RST
minimum capacitance of 500pF should be used, along with a parallel external pull-up resistor of
1kW minimum.
