It contains the basic functionality to supply the microcontroller and the ECU, establish the communication on- and off- board and drive EMS typical actuators. Furthermore it controls the main relay driver. Type Package Marking TLE8888-1QK LQFP-100 TLE8888-1QK TLE8888QK LQFP-100 TLE8888QK TLE8888-2QK LQFP-100 TLE8888-2QK Device Variants TLE8888QK and TLE8888-2QK The device variants TLE8888QK and TLE8888-2QK differ from the main version TLE8888-1QK in the watchdog functionality. The TLE8888QK has a fixed set of parameter for the watchdog (see datasheet addendum TLE8888QK - Addendum). For the TLE8888-2QK the watchdog function is disabled (see datasheet addendum TLE8888-2QK - Addendum). Only the main version TLE8888-1QK is described in this datasheet.
