Abstract:
A ringing peak detector circuit includes an input buffer receives a pair of differential feedback signals indicating a drain-source voltage of the at least one low side electronic switch. The input buffer generates shifted differential feedback signals having a common mode voltage that is equal to approximately one half of the supply voltage. A peak detector circuit is coupled to the input buffer to receive the shifted differential voltage signals. The peak detector circuit detects a peak value of an oscillation on the inductive electric load and to generate an output signal indicating the detected peak value. A circuit generates a control signal based on the detected peak value and a maximum value, with the control signal being applied to the inductive electrical load driver to control switching of the at least one low side switch.

Claim (Index 16):
A method, comprising:\n receiving first and second differential feedback voltage signals, wherein the first and second differential feedback signals indicate a drain-source voltage of a low-side switch contained in a bridge circuit driving an inductive electrical load; coupling the first and second differential feedback voltage signals to first and second input nodes to provide first and second differential feedback voltage signals on the first and second input nodes; shifting levels of the coupled first and second differential feedback voltage signals to provide a common mode of the first and second differential feedback voltage signals that is equal to approximately one half of a supply voltage, the shifted first and second differential feedback voltage signals being shifted first and second differential voltage signals; detecting a peak value of a differential signal formed by the shifted first and second differential voltage signals; and generating a peak ringing output signal based on the detected peak value of the differential signal formed by shifted first and second differential voltage signals and a maximum value.
