and mechanical interface to 1-wire devices. Dallas’ Battery
Instrumentation IC’s use a sub-set of the microLAN standard,
which means, that they use the same communication protocol
(transport layer), but differ with microLAN features, such as
addressability (network layer), overdrive, and
programmability. Due to the nature of a limited battery pack
supply voltage, non-volatile data is stored by using internal
charge pumps - rather than applying external 12V pulses.
Figure 1 display a typical hardware interface, which is used in
our DS3701 Com-Port adapter:
