A circuit must be designed and evaluated not to exceed absolute maximum rating in any cases and even momentarily, to
prevent reduction in functional performances and thermal destruction of a semiconductor product and secure useful life and
reliability.
The following values assume Ta =25℃. For latest values, refer to delivery specifications.
(Note 1) A voltage that can be applied with reference to GND (pins 11, 12, 33, 34, and 43)
(Note 2) Pd and Tjmax=150℃ must not be exceeded.
(Note 3) 70mm × 70mm × 1.6mm FR4 One-sided glass epoxy board (Back copper foil 0%) installed.
(Note 4) 70mm × 70mm × 1.6mm FR4 Both-sided glass epoxy board (Back copper foil 100%) installed.
The following values assume Ta =25℃. Check for latest values in delivery specifications.
(Note 5) Pd should not be exceeded.
Except otherwise specified T
For latest values, refer to delivery specifications.
(Note 6) The rated values of items above indicate average performances of the device, which largely depend on circuit layouts, components, and power
