Parallel SPI Configuration

Engine Management Application

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

and TLE 6220 GP 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 con-

trolled direct in parallel for PWM applications.
