Notes:

14. Current Sense Ratio CSRx = ICSNS / IHS[x]

15. See note (16), but with ICSNS_MEAS obtained after compensation of I_LOAD_ERR_RAND (see Activation and Use of Offset Compensation).

Further accuracy improvements can be obtained by performing a 1 or 2 point calibration.

16. ESRx_ERR=(ICSNS_MEAS / ICSNS_MODEL) -1, with ICSNS_MODEL = (I(HS[x])+ I_LOAD_ERR_SYS) * CSRx , (I_LOAD_ERR_SYS defined above, see

section Current Sense Error Model). With this model, load current becomes: I(HS[x]) = ICSNS / CSRx - I_LOAD_ERR_SYS
