Parallel SPI Configuration

Engine Management Application

TLE 6232 GP in combination with TLE 6240 GP (16-fold switch) for relays and general pur-

pose 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 26 channels in sum 18 can be controlled direct in parallel for PWM applications.
