11. Short-circuit between pins
Turning on the power supply with the short-circuit between terminals leads to the deterioration and destruction of IC.
When fixing the IC to the substrate, please check that the solder is not short-circuited between the terminals before
turning on the power.
12. Load Short-circuit
Leaving the IC in the load short-circuit for many hours leads to the deterioration and destruction of the IC.
The load must not be short-circuited absolutely.
13. Maximum rating
When the rated value used is just below to the absolute maximum ratings value, there is a possibility to exceed the
maximum rating value with slight extrusion variable. Also, it can be a destructive accident.
Please use within the absolute maximum ratings with sufficient variation margin of supply voltage.
In addition, the package of this IC has low thermal radiation characteristics, so secure sufficient thermal radiation by
providing a copper foil land on the printed circuit board near the heat sink.
When VCC = 5V and load = 8Ω, a ground line copper foil area of approximately 50mm × 50mm is recommended.
