◇Cautions on use
(1)
Absolute maximum ratings
If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be damaged. Do not
apply voltages or temperatures that exceed the absolute maximum ratings. If you expect that any voltage or temperature could be
exceeding the absolute maximum ratings, take physical safety measures such as fuses to prevent any conditions exceeding the
absolute maximum ratings from being applied to the LSI.
(2)
GND potential
Maintain the GND pin at the minimum voltage even under any operating conditions.
Actually check to be sure that none of the pins have voltage lower than that of GND pin, including transient phenomena.
(3)
Thermal design
With consideration given to the permissible dissipation under actual use conditions, perform thermal design so that adequate margins
will be provided.
(4)
Short circuit between pins and malfunctions
To mount the LSI on a board, pay utmost attention to the orientation and displacement of the LSI. Faulty mounting to apply a
voltage to the LSI may cause damage to the LSI. Furthermore, the LSI may also be damaged if any foreign matters enter between
pins, between pin and power supply, or between pin and GND of the LSI.
(5)
Operation in strong magnetic field
Make a thorough evaluation on use of the LSI in a strong magnetic field. Not doing so may malfunction the LSI.
