OVERVIEW
The block diagram of Figure 1 shows the seven major components of the DS2438:
1.
2.
3.
4.
5.
6.
7.
64-bit lasered ROM
temperature sensor
battery voltage A/D
battery current A/D
current accumulators
elapsed time meter
40-byte nonvolatile user-memory
Each DS2438 contains a unique 64-bit lasered ROM serial number so that several battery packs can be
charged/monitored by the same host system. Furthermore, other Dallas products featuring the same
1-Wire bus architecture with a 64-bit ROM can reside on the same bus; refer to the Dallas Automatic
Identification Data book for the specifications of these products.
Communication to the DS2438 is via a 1-Wire port. With the 1-Wire port, the memory and control
functions will not be available until the ROM function protocol has been established. The master must
first provide one of four ROM function commands: 1) Read ROM, 2) Match ROM, 3) Search ROM, or 4)
Skip ROM. These commands operate on the 64-bit lasered ROM portion of each device and can singulate
a specific device if many are present on the 1-Wire line as well as to indicate to the bus master how many
and what types of devices are present. After a ROM function sequence has been successfully executed,
the memory and control functions are accessible and the master may then provide any one of the six
memory and control function commands.
