Abstract: A full-bridge circuit module with an over-temperature protection mechanism for driving an inductive load includes a full-bridge circuit and a comparator module. When the over-temperature protection mechanism is triggered, four switching transistors of the full-bridge circuit are turned off, and two body diodes of corresponding twos of the four switching transistors which are electrically connected to each other via the inductive load are conductive to form a load current flowing through the inductive load. When the load current causes a first output voltage of a first output terminal of the full bridge circuit to drop to a first comparison voltage and causes a second output voltage of a second output terminal of the full bridge circuit to reach a second comparison voltage, the comparator module controls the corresponding twos of the four switching transistors which are electrically connected to each other via the inductive load to be turned on.

Abstract: A ramp voltage signal generated by an equivalent series resistance compensation circuit in prior art is not linear, and average amplitude and maximum amplitude of the ramp voltage signal changes with an input voltage and a turn-on time.
