DS1834/A/D
Tolerance Select
The DS1834 provides two TOL inputs for individual customization of the DS1834 to specific application
requirements. 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 generated 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
40 k ? = pull-up resistor and debounced via internal circuitry. See Figure 3 for an application example and
Figure 4 for the timing diagram.
