TLE8888QK

The TLE8888QK from Infineon Technologies is a versatile Engine Machine System IC tailored for automotive engine management. This U-Chip provides essential functionality for supplying microcontrollers and ECUs, facilitating on- and off-board communication, and driving typical EMS actuators.

Key features include a voltage pre-regulator, an integrated 5V regulator, and two additional 5V trackers, alongside a standby regulator. Communication capabilities are robust, with a high-speed CAN interface featuring wake-up by bus and a LIN interface supporting high-speed K-Line operation. It also includes a variable reluctance sensor interface and a Microsecond Channel interface (MSC) with LVDS inputs for low electromagnetic emission.

The device offers extensive output driving capabilities, including multiple low-side power stages for injectors and relays, push-pull stages for MOSFET and IGBT driving, and half-bridge stages for flexibility. Diagnostic features such as open-load, short-to-GND, and short-to-BAT detection are integrated, along with overtemperature and short-to-BAT protection. A monitoring watchdog module enhances system reliability.

Packaged in an LQFP-100, the TLE8888QK is AEC Qualified, making it suitable for demanding automotive environments. Its comprehensive feature set allows it to control the main relay driver and support ignition key detection with key-off delay.
