Application example
(1) Numbers and data in entries are representative design values and are not guaranteed values of the items.
(2)Although we are confident in recommending the sample application circuits, carefully check their
characteristics further when using them. When modifying externally attached component constants before
use, determine them so that they have sufficient margins by taking into account variations in externally
attached components and the Rohm LSI, not only for static characteristics but also including transient
characteristics.
(3) Absolute maximum ratings
If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI
may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If
you think of a case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety
measures and investigate how not to apply the conditions under which absolute maximum ratings are
exceeded to the LSI.
(4) GND potential
Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm
that the voltage of each pin does not become a lower voltage than the GND pin, including transient
phenomena.
(5) Thermal design
Perform thermal design in which there are adequate margins by taking into account the allowable power
dissipation in actual states of use.
