3. Stress Compensation➢ Our most recent current sensors include a stress-compensation circuit to ensure optimal stability
over lifetime.➢ Stresses applied to the Hall sensing elements are automatically compensated by a change of the
biasing current.➢ With this technology, lifetime sensitivity drift is below < 1%
