ELECTRICAL CHARACTERISTICS (CONTINUED)

Electrical Characteristics:

Unless otherwise specified, VDD = 4.5V to 5.5V, VS = 2.9V to 5.5V, VPULLUP = 3V to 5.5V,

TA = -40°C to +85°C; all Typical values at VDD = VS = 5V, TA = +27°C.

Conditions

Note 1:

For split supply systems using the Attach Detection feature, VS must not exceed VDD +150 mV.

This parameter is ensured by design and not 100% tested.

This parameter is characterized, but not 100% production tested.

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).

The Min and Max values represent the boundaries of a programmable range for UCS1003-1 only. Each value

in the range is typical.
