SI-8005Q
In general, the junction temperature level of surface mount pack-
age ICs is dependent upon the area and material of the PC board
and its copper area. Therefore, please design the PCB to allow
sufficient margin for heat dissipation.

Cautions
Thermal Shutdown The SI-8000Q series has a thermal protec-
tion circuit. This circuit keeps the IC from the damage by over-
load. But this circuit cannot guarantee the long-term reliability
against the continuous overload conditions.
ESD Susceptibility Take precautions against damage by static
electricity.
