Parallel SPI Configuration

Engine Management Application

TLE 6230 GP in combination with TLE 6240 GP (16-fold switch) for relays and general purpose loads

and TLE 6220 GP (quad switch) to drive the injector valves. This arrangement covers the numerous

loads to be driven in a modern Engine Management/Powertrain system. From 28 channels in sum 16

can be controlled direct in parallel for PWM applications.
