Notes 1.
Permissible current per phase with the IC mounted on a PCB.
2.
When the IC is mounted on a glass epoxy PCB (10 cm x 10 cm x 1 mm).
Caution
If the absolute maximum rating of even one of the above parameters is exceeded even
momentarily, the quality of the product may be degraded. Absolute maximum ratings, therefore,
specify the values exceeding which the product may be physically damaged. Be sure to use the
product within the range of the absolute maximum ratings.
