1) Shunt Resistor Drift Compensation with Ambient Temperature (Normalized Compensation Factor)
The compensation factor is defined as:
Rcomp=A⋅T2+B⋅T+C
Formula Description:
T: Temperature reading from the PCB-mounted NTC sensor
A: Quadratic coefficient (default: –0.000000305*)
B: Linear coefficient (default: +0.000092070*)
C: Constant term (default: +0.996706113*)
2)Compensated Shunt Resistance:
Rshunt(comp)=R25⋅Rcomp
where R25 is the shunt resistance at 25 °C.
Note: *Values are for reference only.
