DS1831C/D/E
OPERATION—PUSHBUTTON STATUS
The DS1831E 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 W (see Figure 6).

OUTPUT VALID CONDITIONS
The DS1831 can maintain valid outputs as long as one input remains above 1.0V. Accurate voltage
monitoring additionally requires that either the 3.3V IN or 2.5V IN input be above 1.5V. If this condition
is not met and at least one of the supply inputs are at or above 1.0V all outputs are maintained in the
active condition. The DS1831 requires pull-up resistors on the outputs to maintain a valid output. 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 pull-up resistor value used is 10k W (see Figure 7).
