DS1233A
OPERATION — PUSHBUTTON RESET
The DS1233A provides for a pushbutton switch to be connected to the
output pin. When the
RST
DS1233A is not in a reset cycle, it continuously monitors the
signal for a low-going edge. If an edge
RST
is detected, the DS1233A will debounce the switch by pulling the
line low. After the internal timer
RST
has expired, the DS1233A will continue to monitor the
line. If the line is still low, the DS1233A will
RST
continue to monitor the line looking for a rising edge. Upon detecting a release, the DS1233A 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 0.01F must be
connected between
and ground. In applications where additional reset current is required, a
RST
minimum capacitance of 500 pF should be used, along with a parallel external pull-up resistor of 1k
minimum.
