Note 1:
For split supply systems using the Attach Detection feature, VS must not exceed VDD +150 mV.
2:
This parameter is ensured by design and not 100% tested.
3:
This parameter is characterized, but not 100% production tested.
4:
The current measurement full-scale range maximum value is 3.0A. However, the UCS1003-1 cannot report
values above ILIM (if IBUS_R2MIN  ILIM) or above IBUS_R2MIN (if IBUS_R2MIN > ILIM and ILIM 1.68A).
5:
The Min and Max values represent the boundaries of a programmable range for UCS1003-1 only. Each value
in the range is typical.
