TIMING DIAGRAM—5V OR 3.3V PUSHBUTTON RESET

OPERATION—PUSHBUTTON STATUS
The DS1831B provides a master pushbutton status open drain output. The
PBST
output indicates the
status of the most recent reset condition. If the last reset was generated by the master pushbutton input it
would maintain a low condition until cleared by another event (except the master pushbutton) generating
a reset. Once cleared it will remain high until the master pushbutton is pulled low generating a reset
condition. The
PBST
output is open drain and will require a pull-up resistor on the output to maintain a
valid condition. The value of the pull up resistor is not critical in most cases but must be set low enough
to pull the output to a high state. A common value used is 10k (see Figure 6).
