Tolerance Select
The DS1834 provides two TOL inputs for individual cus-
tomization of the DS1834 to specific application require-
ments. If the TOL for the 5 volt supply is tied to the 5 volt
input a 10% tolerance is selected for the 5 volt supply. If
the TOL for the 3.3 volt supply is tied to the 3.3 volt input
a 20% tolerance is selected for the 3.3 volt supply. If
TOL inputs are tied to ground the 5 volt input will be set
at a 5% tolerance and the 3.3 volt input would be set to a
10% tolerance.
Pushbutton Reset
The DS1834 provides a pushbutton switch for manual
reset control. When at least one of the DS1834 resets
are not in a reset cycle, a pushbutton reset can be gen-
erated by pulling the PBRST pin low for at least 2 ms.
When the pushbutton is held low, both resets are forced
active and will remain active for about 350 ms after the
pushbutton is released. The pushbutton input is pulled
high through an internal 40K
pull–up resistor and
debounced via internal circuitry. See Figure 3 for an
application example and Figure 4 for the timing dia-
gram.
