*1 output current is calculated by registance of VCM and

(the drain-source voltage of Nch Driver Tr) + (sense registance voltage).

ex. In the case of "VM=3V" and "output current=100mA"

(the drain-source voltage of Nch Driver Tr) + (sense registance voltage)= max 0.5V.

VCM registance (Rvcm) = (2.8-0.5) / 0.1 = 23Ω

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed,

damage may occur and reliability may be affected.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended

Operating Ranges limits may affect device reliability.
