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.
