When the thermal shutdown circuit is activated at the
chip temperature of about 175_C (typical), the outputs
are left OPEN. The temperature difference between the
activation and deactivation settings is about 15_C. When
the thermal shutdown circuit is deactivated, the outputs
revert to the status determined by input mode.

checked; however, use of the products with applied volt-
ages, operating temperatures, or other parameters that
exceed the absolute maximum rating given may result in
the damage of the IC and the product it is used in. If the
IC is damaged, the short mode and open modes cannot
be specified, so if the IC is to be used in applications
where parameters may exceed the absolute maximum
ratings, then be sure to incorporate fuses, or other physi-
cal safety measures.

The potential for pin 1 must be kept lower than the poten-
tials of the other pins regardless of the circumstances.

Depending on the ambient conditions, environment, or
motor characteristics, the back-rush voltage may fluctu-
ate. Be sure to confirm that the back-rush voltage will not
adversely affect the operation of the IC.
