7.2.2.3 Calculate Returned Values

Parametric values are calculated by multiplying the returned value by the LSB value. Table 7-4 shows the returned values for this application example, assuming the design requirements shown in Table 7-3.

Table 7-4 Calculating Returned Values
PARAMETERRETURNED VALUELSB VALUECALCULATED VALUE
Current (A)10526d190µA2A
Bus voltage (V)3840d3.125mV12V
Power (W)631578d38µW24W
Energy (J)142105263d0.608mJ86.4kJ
Charge (C)606315789d11.875µC7200C
Temperature (°C)320d125mºC40°C

Current, Bus Voltage (positive only), Charge, and Temperature return values in 2's-complement format. In 2's-complement format a negative value in binary is represented by having a 1 in the most significant bit of the returned value. These values can be converted to decimal by first inverting all the bits and adding 1 to obtain the unsigned binary value. This value can then be converted to decimal with the negative sign applied. For example, assume a current reading returns 1011 0100 0001 0000. This is a negative value due to the MSB having a value of one. Inverting the bits and adding one results in 0100 1011 1111 0000 (19440d) which is current value of 3.6936A. The returned value is negative, therefore the measured current value is –3.6936A.
