MC33926AES/MC33HB2000AES/MC33HB2002ES H-Bridge Brushed DC Motor Drivers
NXP introduces H-bridge brushed DC motor drivers for automotive electric vehicle and engine control
NXP's HB2000AES, HB2000ES, and 33926AES series of H-bridge motor drivers feature a 44% smaller HVQFN 6 mm x 6 mm package and improved thermal performance for automotive electric vehicles, internal combustion engine control, and industrial motor control applications.
The market is turning to electrification, for electric vehicles (EV) and internal combustion engines (ICE). The number of electric motors per EV and ICE has increased due to the replacement of hydraulic pumps with electric motors. Five years ago, an engine control unit (ECU) had one to three brushed DC H-bridge motors. Today, you find three, five, seven, or more. This is presenting several issues including space, heat, and cost. NXP offers a solution to these issues with their HB2000AES, HB2000ES, and 33926AES H-bridge motor drivers.
Some of the key features of the HVQFN 28-pin package are smaller size, highly conductive die attach for low thermal resistance to the thermal pad, corner pads for ensured thermal cycling, and inspectable fillets on the bonding pads for visual inspection of the solder joints.
