Note 1: Output current may be controlled by excitation mode, ambient temperature, or heatsink.
When designing a circuit, ensure that the maximum junction temperature, TjMAX = 150°C, is not exceeded
when the IC is used.
Avoid using the IC in abnormal conditions that would cause the Tj to exceed 150°C, even though the heat
protection circuit of the IC will continue to operate in such conditions.
Note 2: When mounted on a board (50 mm
×
50 mm
×
1.6 mm, Cu area: 50%)
The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not be
exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be irreparably
altered, in which case the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in other
equipment. Applications using the device should be designed so that no maximum rating will ever be exceeded under
any operating condition.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth in
this document.
