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 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

直喷发动机的喷油器在开启喷油时需要迅速打开,我们知道喷油器实质是电磁阀, 那么要想快速开启就需要有一个大的电流加载到喷油嘴,但是我们的系统电压只有 一个12V(车载12V电瓶),电磁阀的电感量一定,那个最大的电流能力也一定, 这时要加大电流就需要一个DCDC将12V电压boost 到一个高压(一般是DFI喷油器 设计时boost电压是 65V或 48V)
