Abstract
A circuit for sensing a current in an inductor is described. Integrator circuitry is operable to generate a first signal representing an integration of a voltage across the inductor. Comparison circuitry is operable to generate a reset signal each time the first signal reaches either a positive or negative threshold. The reset signal is for resetting the integrator circuitry. Logic circuitry is operable to generate a count direction signal indicating which of the positive and negative thresholds was reached to generate the reset signal. Counter circuitry is operable to increment or decrement a count representing the current in the inductor in response to the reset and count direction signals.
