Table 3. Static Electrical Characteristics (continued)

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:

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.

18. 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
