Multiply the returned value by the LSB value to calculate the parametric values. Table 7-4 below shows the returned values for this application example assuming the design requirements shown in Table 7-3.
PARAMETER | RETURNED VALUE | LSB VALUE | CALCULATED VALUE |
---|---|---|---|
Current (A) | 15000d, 3A98h | 2.4 mA/LSB | 36 A |
Bus voltage (V) | 15360d, 3C00h | 3.125 mV/LSB | 48 V |
Power (W) | 3600000d, 36 EE80h | 480 µW/LSB | 1.728 kW |
Energy (J) | 202500000d, C11E7A0h | 7.68 mJ/LSB | 1.5552 MJ |
Charge (C) | 13500000d, CDFE60h | 150 µC/LSB | 32400 C |
Temperature (°C) | 680d, 2A8h | 125 m°C/LSB | 85°C |
Current, Bus Voltage (positive only), Charge, and Temperature return values in 2's complement format. In a 2's complement format, a 1 in the most significant bit of the returned value represents a negative value in binary. These values can be converted to decimal by first inverting all the bits and adding 1 to obtain the unsigned binary value. This value must then be converted to decimal with the negative sign applied.
