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.
