Engine Control IC 100-Pin LQFP T/R

The TLE8888QK is the optimum ‘all-in-one-device’ solution, if it’s about automotive engine management systems. It contains all necessary items for an electronic control unit for 4 cylinder automotive engine management systems. TLE8888 includes state of the art communication interfaces, ECU and sensor supply functions and the output drivers for solenoids, injectors, relays and stepper motors. In addition to that there are advanced diagnosis features and functions implemented into the TLE8888 for optimum use in a modern engine management system.
