10. Malfunction may be happened when the device is used in the strong electromagnetic field.
11. We recommend to put Diode for protection purpose in case of output pin connected with large load of impedance or reserve
12. Precautions for board inspection
13. GND pattern
When both a small-signal GND and high current GND are present, single-point grounding (at the set standard point) is
recommended, in order to separate the small-signal and high current patterns, and to be sure the voltage change stemming from
the wiring resistance and high current does not cause any voltage change in the small-signal GND. In the same way, care must
be taken to avoid voltage fluctuations in any connected external component GND.
current occurred at initial and output off.
Connecting low-impedance capacitors to run inspections with the board may produce stress on the IC. Therefore, be certain to
use proper discharge procedure before each process of the test operation. To prevent electrostatic accumulation and discharge in
the assembly process, thoroughly ground yourself and any equipment that could sustain ESD damage, and continue observing
ESD-prevention procedures in all handling, transfer and storage operations. Before attempting to connect components to the test
setup, make certain that the power supply is OFF. Likewise, be sure the power supply is OFF before removing any component
connected to the test setup.
