Operation notes
(1) Application circuit (in the block diagram)
We guarantee the application circuit design, but recom-
mend that you thoroughly check its characteristics in ac-
tual use.
If you change any of the external component values,
check both the static and transient characteristics of the
circuit, and allow sufficient margin in your selections to
take into account variations in the components and ICs.
Note that Rohm has not fully investigated patent rights
regarding this product.
(2) Operating voltage range
Provided that the IC is operated within the recommended
operating voltage range, the operation of the circuit is
guaranteed within the allowed operating temperature
range.
With regard to the values for the characteristics, the rat-
ing values for electrical characteristics cannot be guaran-
teed, but within these ranges there will not be a dramatic
change in the values for the characteristics.
(3)
Notes regarding power dissipation (Pd)
A derating characteristic is provided for power dissipa-
tion. Your design should not require the component to
dissipate more than its maximum allowed power dissipa-
tion over the operating temperature range.
