When used in Brushless DC (BLDC) motor applications the MOSFETs used in the half- or full-bridge driver stages are subjected to high torque currents a few times higher than continuous operating current. Through laboratory evaluation and power loss analysis, this application note demonstrates that the DMC4040SSD, a 40V complementary pair MOSFET, remains within its maximum junction temperature rating when evaluated in the demanding environment of the consumer printer.
