K_RBAT_SOC

R/W

Battery internal resistance coefficient less than 20% capacity.

00 = RBAT at 0% SOC = RBAT at 20% SOC.

01 = RBAT at 0% SOC = 2 × RBAT at 20% SOC.

10 = RBAT at 0% SOC = 4 ×RBAT at 20% SOC.

11 = RBAT at 0% SOC = 8 × RBAT at 20% SOC.

[3:0]

K_RBAT_CHARGE

R/W

1000

Battery internal resistance coefficient for charging. The coefficient =

0.75 + K_RBAT_CHARGE/32.

BAT_TEMP

R/W

11011

Battery temperature from I2C. The program battery temperature range

is between −2°C and +61°C. Temperature value (°C) = (BAT_TEMP − 2).
