... Battery voltage sense To detect undervoltage conditions at the battery a sense comparator block is available within the TLE 6389. The voltage at the SI input is compared to an internal reference of typ. 1.25V. The output of the comparator drives a NMOS structure giving a low signal soon as the voltage at SI decreases below this threshold. In the 5V fixed version an internal pull up resistor is connected from the drain of the NMOS to the output of the buck converter, in the variable version SO is open drain ...
