Abstract
A current sense method comprises generating a voltage across a first current mirror of a current sense apparatus, the voltage being proportional to a current flowing through the current sense apparatus when the current is greater than a predetermined current value and applying a minimum drain-to-source voltage limiter to the first current mirror of the current sense apparatus when the current is less than the predetermined current value, wherein, as a result of applying the minimum drain-to-source voltage limiter to the first current mirror, the voltage across the first current mirror is clamped to a predetermined voltage value.
