Trim voltage (VNOM). The nominal cell voltage is programmed to nonvolatile memory during
test and loaded to the Trim Voltage register at power up. The VNOM value is a 7-bit
representation of the 0V to 5V cell voltage input range with 50 (7’h32) representing 5V (e.g.,
LSB = 0.1V). The parts are additionally marked with the trim voltage by the addition of a two
digit code to the part number e.g., 3.3V is denoted by the code 33. (1 bit per 0.1V of trim
voltage, so 0 to 50 decimal covers the full range.)

DESCRIPTION
6’h20 - 6’h37
Cell balance registers. These registers are loaded with data related to change in SOC desired for each cell.
This data is then used during Auto Balance mode. The data value is decremented with each successive ADC
sample until a zero value is reached. The register space is arranged as 2 x 14-bit per cell for 24 x 14-bit total.
The registers are cleared at device power up or by a Reset command. See “Auto Balance Mode” on page 47.

Reference Coefficient C
Reference calibration coefficient C LSB. Use with coefficients A and B and the measured reference value to obtain
the compensated reference measurement. This result may be compared to limits given in the “Electrical
Specifications” table to check that the reference is within limits. The register contents may be read by the user but
not written to.
