（１） About absolute maximum rating
（２） About GND Voltage
（３） About design of overheating malfunction preventive circuit
（４） About the short between terminals and the mounting by mistake
（５） About operation in strong electromagnetic field
（６） Please note not to be beyond the package permissible range, When SPVDD is set.
（７） About charge pump
For prevent the undetermined state of charge pump, recommend to put together CPVDD and DVDD pins.
And to avoid the IC’s broken or smoke, you must not supply the external voltage or current to C1, C2, C3, C4, and VEE pins.
When the absolute maximum rating such as the applied voltage and the ranges of the operating temperature
is exceeded, LSI might be destroyed. Please apply neither voltage nor the temperature that exceeds the
absolute maximum rating. Please execute physical measures for safety such as fuse when it is thought to
exceed the absolute maximum rating, and examine it so that the condition to exceed the absolute maximum
rating is not applied to LSI.
In any state of operation must be the lowest voltage about the voltage of the terminal GND. Please actually confirm the voltage of each terminal is not
a voltage that is lower than the terminal GND including excessive phenomenon.
Please design overheating malfunction preventive circuit with an enough margin in consideration of a permissible loss in the state of using actually.
Please note the direction and the gap of position of LSI enough about LSI when you mount on the substrate. LSI might be destroyed when mounting by
mistake and energizing. Moreover, LSI might be destroyed when short-circuited by entering of the foreign substances between the terminal and GND,
between terminals, between the terminal and the power supply of LSI.
Use in strong electromagnetic field has the possibility of malfunctioning and evaluate it enough, please.
