via the RxD output. The over-current condition is monitored on the SPI OBIT 6 in normal
operation mode.
The SPI OBIT 0 flags a thermal pre-warning of the high side switch. By this the
microcontroller is able to reduce the power dissipation of the TLE6263 by switching off
functions of minor priority until the temperature threshold of the thermal shutdown is
reached. Further OUTHS is protected against short circuit and overload. As soon as the
under-voltage condition of the supply voltage is met (V_S < V_UVOFF), the switch is
automatically disabled by the under-voltage lockout circuit. Moreover the switch is
automatically disabled when a reset or watchdog reset occurs.
