Product Brief TLE8080 One Chip Engine Management Power Interface Solution for Small 1 Cylinder Engines Key Features The TLE8080EM is an Engine Management System IC which includes basic functionality to support 1 cylinder combustion engines with focus on the state-of–the-art technology Electronic Fuel Injection (EFI). 5V and reset 2 The TLE8080EM contains a 5V power supply with current up to 250mA, a K-line transceiver and 5 power stages, a variable reluctance sensor interface and features a SPI for control and diagnosis. supply including watch dog low-side drivers for fuel injector and valves 1 low-side driver for multifunction Indication lamp Basic protection and diagnosis features are included: Overtemperature, overcurrent 2 protection, undervoltage reset and open-load in Off. K-line relay drivers transceiver Variable Reluctance Sensor interface SPI Applications 4 stroke small combustion engine for: Motorcycle, Watercraft, 2- and 3- wheelers and scooters marines and jet-ski Snow mobiles, lawn-tractors or -mowers Small gasoline power generating sets [ www.infineon.com/motorcycle ] control Key Benefits Small 150 mil SSOP-24 package saves board space One chip solution Qualified according automotive standard AEC-Q100 Product Brief TLE8080 Block Diagram TLE8080EM A 5V voltage regulator provides up to 250mA VS current and features under-voltage reset, power-on 5V Voltage Supply Undervoltage Detection WD_DIS CSN; SI; SO; SCLK V5DD 4 SPI Watchdog against over-load, short circuit and overtemperature conditions. With an active reset all power stages and NRO Reset reset and watchdog. It includes protection circuits the K-line output are disabled and SPI commands are ignored. The K-line transceiver is a serial link bus interface. It Relay 2 OUT5 provides bi-directional half-duplex communication interfacing using the special ISO K-line and meets LS Driver the ISO norm 9141 specification. The K-line bus Relay 1 OUT4 output is protected against bus shorts and overtemperature conditions. LS Driver 5 low-side channels are optimized for the use in Valve IN3 OUT3 engine management systems. Recommended loads are: LS Driver 2 MIL OUT2 LS Driver Injector IN1 OUT1 LS Driver 2 VR_IN1; VR_IN2 solenoids 1 channel for lamps or LEDs 2 channels for relays The Variable Reluctance Sensor (VRS) interface converts an output signal of a VRS into an 5V logic VR_OUT VR Sensor 2 Rx; Tx channels for Injector valves or similar sized KIO K-Line AGND level compatible to 5V input ports of an micro controller. The diagnosis and control interface is based on a Serial Peripheral Interface (SPI).The SPI is a 16-bits PGND full duplex synchronous serial slave interface.
