Usage notes
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.
2. Please pay attention in the pattern layout in order to prevent damage due to short circuit between pins.
In addition, for the pin configuration, please refer to
Pin Descriptions.
3. Please absolutely do not mount the LSI in the reverse direction on to the printed-circuit-board.
It might be damaged when the electricity is turned on.
4. Please do a visual inspection on the printed-circuit-board before turning on the power supply, otherwise damage might happen
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.
5. Please take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as
output pin, pin 34 and pin 36 (capacitor connect pin 1, 2 for charge pump), pin 38 and pin 39 (V
SS
)
power supply pin short,
output pin, pin 34 and pin 36, pin 38 and pin 39
GND short, or output-to-output-pin short (load short), pin 34
pin 36 short.
And, safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and
smoke emission will depend on the current capability of the power supply.
6. When using the LSI for model deployment or new products, perform fully the safety verification including the long-turm
reliability for each product.
