TLE8080EM Engine Management ICs for Small Engines Infineon Technologies TLE8080EM Engine Management ICs for Small Engines are manufactured using Infineon's Smart Power Technology (SPT). The ICs are protected by embedded protection functions. A power supply is integrated along with a K-line, SPI, variable reluctance sensor interface, and power stages to drive different loads in an engine management system. The TLE8080EM provides a compact and cost-optimized solution for engine management systems. The ICs are very suitable for one-cylinder motorcycle engine management systems.
