Operational Notes
1. Described numeric values and data are design representative values only, and the values are not guaranteed.
2. We believe that the application circuit examples in this document are recommendable. However, in actual use, confirm
characteristics further sufficiently. If changing the fixed number of external parts is desired, make your decision with
sufficient margin in consideration of static characteristics, transient characteristics, and fluctuations of external parts
and our LSI.
3. Absolute maximum ratings
If the absolute maximum ratings such as supply voltage, operating temperature range, and so on are exceeded, LSI
may be destroyed. Do not supply voltage or subject the IC to temperatures exceeding the absolute maximum ratings.
In case of fear of exceeding the absolute maximum ratings, take physical safety countermeasures such as adding
fuses, and see to it that conditions exceeding the absolute maximum ratings should not be supplied to the LSI.
4. GND electric potential
Set the voltage of GND terminal lowest at any operating condition. Make sure that each terminal voltage is not lower
than that of GND terminal.
5. Thermal design
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in
actual operating conditions.
6. Short between pins and mounting errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong
orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins.
7. Operating the IC in the presence of strong electromagnetic field may cause malfunction, therefore, evaluate design
sufficiently.
