ModelGauge m3 Registers
To calculate accurate results, ModelGauge m3 requires
information about the cell, the application, and real-time
information measured by the device.
Figure 8 shows all
inputs and outputs to the algorithm grouped by category.
Analog input registers are the real-time measurements
of voltage, temperature, and current performed by the
device. Application-specific registers are programmed
by the customer to reflect the operation of the applica-
tion. The Cell Characterization Information registers
hold characterization data that models the behavior of
the cell over the operating range of the application. The
Algorithm Configuration registers allow the host to adjust
performance of the device for their application. The Save
and Restore registers allow an application to maintain
accuracy of the algorithm after the device has been
power cycled. The following sections describe each
register in detail.
