Abstract
A driving circuit for an N-channel or NPN-type high-side transistor includes: a level shift circuit configured to level-shift an input signal; and a buffer configured to drive the N-channel or NPN-type high-side transistor according to an output of the level shift circuit, wherein the level shift circuit includes: a differential conversion circuit of an open drain type configured to convert the input signal into a differential signal; a latch circuit configured to perform a state transition with a differential output of the differential conversion circuit as a trigger; and an assist circuit configured to inject an assist current into the latch circuit in synchronization with the input signal.
