1-Wire BUS SYSTEM
The 1-Wire bus is a system which has a single bus master and one or more slaves. The DS2437 behaves
as a slave. The discussion of this bus system is broken down into three topics: hardware configuration,
transaction sequence, and 1-Wire signaling (signal types and timing).
HARDWARE CONFIGURATION
The 1-Wire bus has only a single line by definition; it is important that each device on the bus be able to
drive it at the appropriate time. To facilitate this, each device attached to the 1-Wire bus must have open
drain or 3-state outputs. The 1-Wire port of the DS2437 (DQ pin) is open drain with an internal circuit
equivalent to that shown in Figure 8. A multidrop bus consists of a 1-Wire bus with multiple slaves
attached. The 1-Wire bus requires a pullup resistor of approximately 5 kΩ.
