The TLE 6210 and TLE 6211 are integrated circuit consisting of a 5 V voltage regulator with 800 mA current capability, different relay driver outputs and supervision logic. The supervision logic watches the input voltage and the regulator output voltage both for over-voltage and under-voltage. In addition two window watchdogs supervise the correct operation of 2 independent watchdog signals, e.g. from two Microcontrollers. The TLE 6210 and TLE 6211 are designed especially for the severe conditions of ABS/ ASR applications in an automotive environment.
