IC Usage Considerations
Notes on handling of ICs
[1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded,
even for a moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury
by explosion or combustion.
[2] Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case of
over current and/or IC failure. The IC will fully break down when used under conditions that exceed its
absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise
occurs from the wiring or load, causing a large current to continuously flow and the breakdown can lead
smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown, appropriate
settings, such as fuse capacity, fusing time and insertion circuit location, are required.
[3] If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the
design to prevent device malfunction or breakdown caused by the current resulting from the inrush
current at power ON or the negative current resulting from the back electromotive force at power OFF. IC
breakdown may cause injury, smoke or ignition.
Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable, the
protection function may not operate, causing IC breakdown. IC breakdown may cause injury, smoke or
ignition.
[4] Do not insert devices in the wrong orientation or incorrectly.
Make sure that the positive and negative terminals of power supplies are connected properly.
Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding
the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by
explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation or
incorrectly even just one time.
[5] Carefully select external components (such as inputs and negative feedback capacitors) and load
components (such as speakers), for example, power amp and regulator.
If there is a large amount of leakage current such as input or negative feedback condenser, the IC output
DC voltage will increase. If this output voltage is connected to a speaker with low input withstand voltage,
overcurrent or IC failure can cause smoke or ignition. (The over current can cause smoke or ignition from
the IC itself.) In particular, please pay attention when using a Bridge Tied Load (BTL) connection type IC
that inputs output DC voltage to a speaker directly.
