DS2401

The idle state for the 1-Wire bus is high. If, for any reason, a transaction needs to be suspended, the bus

MUST be left in the idle state if the transaction is to resume. If this does not occur and the bus is left low

for more than 120µs, one or more of the devices on the bus may be reset.

Note:

Depending on the 1-Wire communication speed and the bus load characteristics, the optimal pullup

resistor (RPU) value will be in the 1.5kΩ to 5kΩ range.
