Unless specified otherwise: 8.0 V ≤ VPWR ≤ 36 V, 3.0 V ≤ VDD ≤ 5.5 V, - 40 °C ≤ TA ≤ 125 °C, GND = 0 V. Typical values are
average values evaluated under nominal conditions TA = 25 °C, VPWR = 28 V & VDD = 5.0 V, unless specified otherwise.

Notes:
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
17. 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.
