Cautions on use
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.
6) Shorts between pins and misinstallation
When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is
misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign
substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND.
7) Operation in strong magnetic fields
Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.
