Introducing a new Brushed DC motor driver product family designed for automotive engine control applications. It will be the first motor driver fully certified to ISO26262 to support ASIL level D system qualification and features a patented thermal management scheme to ensure high, efficient operation. The key aspects of thermal power dissipation during heavy load conditions will be reviewed. The session will also include a demonstration with the new brushed dc motor driver and SPI GEN software, showing its integrated protection features. The participants will be able to see how current averaging will maintain higher torque during over-load and all the safety features that can be reported over the SPI.

Hello All, I would like to share a bare board I designed to test one of our H-bridges. The design is based in the MC33926​ which is a DC motor driver, capable of handling up to 5A and 5 to 28v. The microcontroller I used to drive the H-bridge was the S08PA16 ​an 8-Bit, 5v microcontroller with Robust GPIO and high drive capability. Since I wanted to use this board for another projects, I leave access to 6 GPIO and 2 ADC-CH. The schematic and board design are compatible with CADSOFT EAGLE. I modified the Element14 library to add the uC and the H-bridge. I sent the gerber files to OSH Park, and hand solder everything to the board using solder paste. The uC was programmed with a Multilink BDM​. MC33926 Bare board Mounted devices The DC motor I was using did not require more than 3amps. However, the MC33926 is designed to handle up to 5amps and since I will use this board for any other project involving a DC motor, I designed a custom aluminum heatsink and manufacture it with a milling machine. The holes in the heatsink are centered with the VCC and DC-Motor connector screws, hence neither the connector screws or the header pins are in contact with the heatsink. I used thermal grease to properly mount the device on its heatsink. Final board: I hope this information helps anyone who would like to use our H-bridges. Please do not hesitate to contact me if you have any question. Regards, Josh

The PT2000 is NXP's latest generation of solenoid driver solutions targeted for direct fuel injection (DFI) applications. The flexibility and capability of the PT2000 means it can be used to drive other loads in powertrain applications, including VVT, fuel pumps, and other DC motor loads. This technical session will provide an overview of the key features and capabilities of the PT2000, the software development tools, hardware and application. Examples for using the PT2000 for DFI and other power train applications will be discussed.

Demo This demo shows two H-Bridge Brushed DC Motor drivers (HB2000 and HB2001) in action. The drivers were designed for high reliability, high quality, and safety applications. The demo shows how an increase of current will trigger the shutting down of the motor, hence demonstrating one of the safety features of the product.   Products HB2000| SPI Programmable 10A H-Bridge Brushed|NXP  HB2001| SPI Programmable 10A H-Bridge Brushed|NXP  H-Bridge, Stepper and Motor Drivers|NXP 

File attached is a deep training on all PT200x family, showing how to program those devices using microcode. Microcode examples related to this training are avialable on nxp.com on PT2001 or PT2000 pages.   This training is mainly valid for PT2001 but can also be applied to PT2000 and MC33816

Demo This demo shows a typical 4 cylinder direct fuel injection (DFI) application with a high-pressure (HP) fuel pump valve. It introduces the many flexible hardware, voltage and current monitoring, and diagnostic capabilities incorporated into the PT2000. In particular, it provides a demonstration of the PT2000’s integrated real-time End of Injection [EOI] detection function, which enables precise volumes of fuel to be delivered to each cylinder, even as the injector’s characteristics vary over time. Examples showing how the user can implement these programmable capabilities for their specific applications are demonstrated through the associated software IDE and device simulator. A comparison between simulator results and actual results will be shown.     Features: Control 3, 4, 5 or 6 injector or pump solenoids in two or three bank configuration with a 72 V  boost voltage Integrated End Of Injection (EOI) measurement for precise real-time control Security and safety through integrated code encryption Complete PT2000 Development Tool Suite (Simulator, IDE, Tracer, EVB) Flexibility to implement standard or unique peak & hold current waveforms   _________________________________________________________________________________________________________________________________________   Product Link PT2000 https://www.nxp.com/products/power-management/motor-and-solenoid-drivers/powertrain-and-engine-control/programmable-solenoid-controller-gate-driver:PT2000?&tid=vanPT2000 PT2000 Evaluation Kit with KL25Z for 4/6 Cylinder PT2000 Evaluation Kit for 4/6 Cylinder | NXP    Featured: PT2000 IDE: Developer Studio Design Simulator Environment for PT2000 PSC   _______________________________________________________________________________________________________________________________________                                                            4 Cylinder + Fuel Pump Demonstration        A16
