Note 1:
All voltages are referenced to VSS.
Note 2:
Factory-calibrated accuracy. Higher accuracy can be achieved by in-system calibration by the user.
Note 3:
Accumulation bias and offset bias registers set to 00h. NBEN bit set to 0.
Note 4:
Parameters guaranteed by design.
Note 5:
CP pin externally driven to 10V.
Note 6:
Overvoltage and undervoltage delays (tOVD, tUVD) are reduced to 0s if the OV or UV condition is detected within 100ms of entering
Active mode.
Note 7:
tUVD MIN determined by stepping the voltage on VIN from VUV + 250mV to VUV - 250mV.
