TLE8080EM Engine Management IC for Small Engines 1 Overview Features Supply 5 V (+/-2%), 250 mA K-line transceiver (ISO 9141) Serial Peripheral Interface (SPI) 4 low side driver for inductive loads with overtemperature and overcurrent protection and open load/short to GND in off diagnosis: 2 low side switches with maximum operation of 2.6 A 2 low side switches with maximum operation of 350 mA 1 low side driver for resistive loads with maximum operation current of 3 A including overtemperature and overcurrent protection Configurable variable reluctance sensor interface Reset output and 5 V undervoltage detection Watchdog Green Product (RoHS compliant) AEC Qualified Description The TLE8080EM is an engine management IC based on Infineon Smart Power Technology (SPT). It is protected by embedded protection functions and integrates a power supply, K-line, SPI, variable reluctance sensor interface and power stages to drive different loads in an engine management system. It provides a compact and cost optimized solution for engine management systems. It is very suitable for one cylinder motorcycle engine management systems. TLE8080-2EM and TLE8080-3EM TLE8080-2EM differs from the main version in parameters V5DD reset threshold for TLE8080-2EM and TLE8080-3EM and Power on reset delay time for TLE8080-2EM in Chapter 5.4. TLE8080-3EM differs from the main version in parameter V5DD reset threshold for TLE8080-2EM and TLE8080-3EM in Chapter 5.4.
