Infineon Technologies AG today launched the world’s smallest engine management ICs, saving up to two-thirds of board space in control systems for two- and three-wheelers compared to today’s solutions. The new TLE808x device family provides all the functionality required for state-of-the-art electronic fuel injection (EFI) in one-cylinder combustion engines.
The TLE808x family was specifically developed to improve emission and fuel efficiency of four-stroke small combustion engines used in motorcycles, scooters and three-wheelers, lawn tractors and lawn mowers, small gasoline power generators, and marine vehicles, jet-ski- and snow mobiles.
Currently, the TLE808x family includes two devices available in high-volume: The TLE8088 and the TLE8080 with Variable Reluctance Sensor (VRS) interface and enhanced functionality.
In many fast-growing countries in Asia, Africa and South America, motorcycles are the most popular and affordable mode of transportation. However, a traditional carburetor motorcycle has a higher global warming potential than the average automobile. To meet ever stricter exhaust gas and fuel efficiency regulations of motorcycles, highly integrated and cost-effective electronic fuel injection systems must be introduced for small combustion engines. The new TLE808x engine management solutions of Infineon support this development.
The TLE8080 connects the system microcontroller with peripheral sensors, handles signal conditioning, and drives the actuators required for a small combustion engine. It includes a voltage regulator that is required for supplying a microcontroller. The 5-V voltage regulator provides up to 250mA current and features undervoltage reset, power-on reset and watchdog functionality.
In addition, the TLE8080 includes the interface for the variable reluctance sensor (VRS) which measures the Revolutions Per Minute (RPM) of the engine. The interface IC conditions the noisy sensor output signal to the logic input levels required from the microcontroller. Via SPI, two relay drivers and the malfunction indication lamp as well as the VRS interface can be controlled. Two additional low-side switches with direct input pins are included for solenoid valves supporting fuel injectors, choke valves or similar inductive loads. The TLE8080 is the smallest product on the market with this rich feature set.
Availability and packaging
The TLE808x devices are available in production volumes. They come in a space-saving 24-pin Shrink Small Outline Package (SSOP).
Infineon’s product portfolio covers all required electronics for setting up an electronically controlled combustion engine: i.e. the 16-bit microcontrollers of the XC2700 family or 8-bit microcontrollers of the XC800A family, pressure sensors such as KP254, and stepper motor driver ICs such as the TLE8444.
