Abstract

A circuit (100) to drive an inductive load (30), said circuit comprising, a driving switch (10) connected in series with said inductive load (30), a freewheeling switch (20) connected across said inductive load (30), a switch controller (50) coupled to the driving switch (10) and the freewheeling switch (20) for controlling switch ON/OFF of the driving and freewheeling switches (10, 20) to control operation of said inductive load (30), said circuit characterized in that a sensing means (61) to sense the voltage at a high side (35) of the inductive load (30) when switch OFF of said driving switch (10) is detected and said switch controller (50) adapted to switch ON said freewheeling switch (20) based on said sensed voltage at high side (35) of said inductive load (30) .
