Usage Notes
2. Please pay attention in the pattern layout in order to prevent damage due to short circuit between pins.
3. Please absolutely do not mount the LSI in the reverse direction on to the printed-circuit-board.
4. Please do a visual inspection on the printed-circuit-board before turning on the power supply, otherwise damage might happen
5. When using the LSI for model deployment or new products, perform fully the safety verification including the long-turn
6. Note of soldering for heat dissipation
1.Please carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the
conditions of power supply, load and surrounding temperature.
Although indicated also in the column of the maximum rating, the maximum rating becomes an instant and the marginal value
which must not exceed. It sufficiently evaluates, and I use-wish-do so that it may not exceed certainly.
Moreover, don't impress neither voltage nor current to Pin which is not indicated. It may destroy in both cases.
In addition, for the pin configuration, please refer to the
It might be damaged when the electricity is turned on.
due to problems such as a solder-bridge between the pins of the semiconductor device.
Also perform a full technical verification on the assembly quality, because the same damage possibly can happen due to
conductive substances, such as solder ball, that adhere to the LSI during transportation.
