Brushless DC-Motor Driver IC Efficiently Drives Pumps in Vehicles
Originating from the high-end RC toys world (cars, planes, boats…), Brushless-DC motors (BLDC) are replacing older brushed DC motors in various industries. Obvious advantages are a longer lifetime and higher efficiency, but motor control is more complicated. MinDCet was the partner of choice for Melexis to implement a monolithic 40V / 3A peak sensor-less BLDC motor drivers. By integrating the sensing, controlling, gate-driver and power-stages into a single chip, a significant reduction in bill-of-material and cost was achieved.
