Cluster temperatures information is available in the SPI registers and can be calculated from the binary coded

Decimal= 358.26−Tj

0.488

(1)

Tj=358.26−Decimal×0.488

(2)

We can get this information:

T = -40 °C → decimal code is 816 (0x330, read out from SPI register)

T = 25 °C → decimal code is 683 (0x2AB, read out from SPI register)

Read out SPI register 0x330, means the decimal is 816 → T = -40 °C

Read out SPI register 0x2AB, means the decimal is 683 → T = 25 °C

Also VBATx can be read from 0 to 22 V (above 22 V the ADC output doesn't change):

Decimal=46.55×VBATxx=1,2−1

(3)

VBATx=decimal+1

46.55

(4)

Example:

VBAT1 = 14 V→ decimal code is 651 (0x28B, read out from SPI register)

Read out SPI register 0x28B, means the decimal is 65 → VBAT1 = 14 V
