Abstract

An HS switching transistor is coupled between a high-side node and a switching node. An LS switching transistor is coupled between the switching node and a low-side node. An inductive load is coupled to the switching node in a way where one of the HS/LS switching transistors is freewheeling. In response to detection of a short circuit occurring at the switching node with the freewheeling switching transistor in the conductive state: an electrical signal at the switching node is sensed, a comparison is made between the sensed electrical signal and a threshold level, and a driving signal is provided to control freewheeling switching transistor to switch to the non-conductive state when the comparison indicates that the electrical signal has reached the threshold level.
