... In BD6512F/BD6513F/BD6516F/BD6517F, the switches of both OUTA and OUTB become off and error flags are output to the both. BD2042AFJ/ BD2052AFJ have dual thermal shutdown threshold. Since thermal shutdown works at a lower junction temperature when an overcurrent occurs, only the switch of an overcurrent state become off and error flag is output. ...
