數(shù)據(jù): NXP Semiconductors PT2001 Programmable Solenoid Controller (PSC).pdf
NXP半導體PT2001可編程螺線管控制器(PSC)是一種用于精密汽車螺線管控制應(yīng)用的SMARTMOS柵極驅(qū)動器集成電路,其目的是使主微控制器擺脫執(zhí)行器控制的繁重任務(wù)。 PT2001包括每個高壓直流到直流轉(zhuǎn)換器預河的單獨電荷泵輸出。 門驅(qū)動、診斷和防止外部故障的保護通過四個獨立和并發(fā)的數(shù)字微芯片進行管理。 這兩個邏輯通道中的每個通道包括兩個微芯片和它們自己的代碼RAM和數(shù)據(jù)RAM。
The internal microcode of the PT21001 is protected against theft via encryption and corruption via checksums. Those microcores are optimized to control power MOSFET with a small latency time. The microcores also enable moving the computation from the MCU to PT2001, clearing the MCU for other critical tasks. The PT2001 can control two banks of two/three injectors each.
