Functional Description

The TLE6212 is a system IC intended for ABS, Traction Control and Electronic Stability Control Systems. It is

especially designed for automotive use. The device is based on Infineon’s power technology SPT4 which allows

bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry.

The TLE6212 includes different functions needed for ABS, TC and ESC systems as Wheel Speed Sensor

Interface both for active or passive sensors, multiple supply control for the micro controller and other components

on the PCB, High Side Driver for Pump Motor and Main switch. High voltage enable and general purpose outputs

and K-Line interface is available for off-board communication. A 8 bit SPI interface allows communication and

programming from the micro controller.

For safety reasons a window watchdog / signature watchdog is included. In addition a logic backbone connects

all sub-blocks and its supervision functions to each other and to the SPI communication interface.
