Automotive Fuel Injector Control Using Power+ Control With Power+ Arrays


The automotive industry is faced with increasingly strict environmental regulations which require that automotive module designs include real-time monitoring and off-line fault isolation. These requirements demand that protection and fault diagnostics be present in the module to help monitor emission levels and maintain system reliability. One area that is very sensitive to these requirements is the automotive powertrain. With today?s highly specialized fuel systems, fuel injector drive is of key interest. Texas Instruments has introduced four new devices, the TPIC46L01/02 and TPIC44L01/02, that are well-suited for fuel injector control applications. The 6-channel TPIC46L01/02 and the 4-channel TPIC44L01/02 are low-side pre-FET drivers capable of serial or parallel interface.
