Note 1. These parameters can drift by long-term use or reflow process. Please see ‘14. Reliability Tests’ for the
reference of drift values.
Note 2. The primary current (I_IN) is swept within ±6A. Current is applied within 35ms in each step.
Note 3. This parameter is tested on condition that current density is uniform. Sensitivity may change slightly
depending on a primary conductor layout on PCB. Please see the application note provided in the
AKM website.
Note 4. These parameters are guaranteed by design.
