DS1836A/B/C/D
OUTPUT VALID CONDITIONS
The DS1836 can maintain valid outputs as long as one input remains above 1.2V. However, the
RST
outputs on the DS1836A (or C) use a push-pull output structure which can maintain a valid output below
1.2V on an input. To sink current below 1.2V a resistor can be connected from
to GND (see Figure
RST
5). This arrangement will maintain a valid value on the
outputs even if all supply inputs are at 0V.
RST
During conditions when the
is in the inactive or high state this arrangement will draw current
RST
through the pull down resistor. A value of about 100 kΩ should be adequate to maintain a valid condition.
The DS1836
output requires a pull-up resistor on the output to maintain a valid output. The value of
NMI
the 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 10kΩs (see Figure 3).
