Notes:
1）AEC-Q200 qualified.
2）All test data is referenced to 25℃ ambient.
3）Operating temperature range -40℃ to +125℃.
4）Isat: DC current(A) that will cause lo to drop approximately 35%.
5）The part temperature(ambient + temp rise)should not exceed 125℃ under worst case operating
conditions. circuit design,component placement, PWB trace size and thickness,airflow and other
cooling provisions all affect the part temperature,part temperature should be verified in the end
application.
