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.

2: The current measurement full-scale range maximum value is 2.5A. However, the UCS1002-3 cannot

report values above ILIM (if IBUS_R2MIN  ILIM) or above IBUS_R2MIN (if IBUS_R2MIN > ILIM and ILIM 1.5A).
