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

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 

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.

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）

1. Add 1.5µF or 2.2µF ​100V capacitor between B+A and GND. Better performance of X7R capacitor. 2. connect backside of die to AGND. both of these two recommendations are for EMC concern.​ If die has no back metal. we recommend customer use epoxy technology (silver glue), and also connect backside to GND​. For epoxy technology (silver glue 银浆工艺)， please refer to attachment.

For die sales products, we only accept CQC that already no gel above the die. Because: Before starting FA, we need to remove the die from brush holder or PCB. And then rebond into a special package. If gel is not removed, the die cannot be rebond. Please make sure the die is totally gel removed. Otherwise, FA cannot do wire bond.

If we take the example of a 100A alternator and a blind zone at 12%. 100% DC corresponds to 100A load on the stator, so that means the LRC will be started only if the load increase is more than 12A. This is a rough estimation that does not take into account the alternator efficiency (which is low at low speed).

In pre excitation mode 2, you can have any duty cycle between pre exc value and 100% depending on battery and Vset voltage. On some alternators, with high duty cycles, the switching of excitation causes so much noise through the phase that this noise can be interpreted as valid phase signal. Thus, the device can go to regulation. To avoid that, we added the ability to deglitch the phase input only in pre excitation mode 2 to be sure that the signal we have are real phase signals. Depending on the duration of the noise our customer can see during pre excitation mode2, they can set the value of deglitcher. If they don't use pre excitation mode2, this value is "don't care".      

Blind Zone is designed a current gap when excitation start raising at very beginning.  This feature is designed for a mechanical coupling delay time when engine start. Customer can fuse the blind zone as initiation, or config/inhibit blind zone by LIN command. Customer can refer to the attachment truth table find the blind zone result.   LIN have higher priority. when BZI(OTP)=BZI(LIN)=1, BZ output=0% For other cases: 1. LIN mode: BZ=BZ(LIN) 2.

MC33AR6000(LIN2112 is nick name) have advanced Excitation current feedback and protection. But different current value is been used in different condition. 1. Current measurements: Excitation control is a MOS ON/OFF PWM. During MOS ON, current raise, during MOS OFF, current decrease, as motor parasitic inductance. Current measurement only happens during MOS ON. IC catch sample current value Sn in every 10-15us, . When MOS OFF, current measurement value Iexc=ΣSn/n.  2. Iexc current feedback by LIN MC33AR600 can report Iexc value by LIN. The report value Iexc_LIN= ΣIexcx/X, X is number of excitation cycles happens during two LIN current command. 3. Current limitation current limitation is compare Iexc to Iexc_limit threshold. Be careful, Iexc is an average value. Iexc>Iexc_limit trigger limitation on next excitation cycle. So current limitation dose not mean limitation action happen once current real time value reach the limitation threshold.     EXC current measurement: 1. sampling Iexc every 10-15μs when MOS ON. (S0,S1,...Sn) 2. calculate average value of the sampes in one period. ( D=(S0+S1+S2+..Sn)/n) 3.report D to digital core. D = Iexc. 4. calculate average of D value in Ffilter_Iexc (selected by OTP) period. Reprot to ECU by LIN. (Iexc_LIN=(D0+D1+...Dx)/X    EXC current limitation: 1. once detect Iexc(D)>Ilimit, the duty cycle(DC) in next period is minimum duty cycle(celected by OTP). 2.  once Iexc<Ilimit , the next duty cycle back to normal regulation DC. -- other words, the current limit function is refreshed by regulation requency(200Hz).
