... Sleep Mode The TLE 8444SL can be placed in low current-consumption mode (or sleep mode) by setting the input, INH pin to LOW. The INH pin has an internal pull-down current source. In sleep-mode, all output transistors are switched off. An output disable and enable time is specified and this behavior is shown in ...

... Reverse Polarity The TLE 8444SL requires an external reverse polarity protection. This protection is essential to avoid an undesired I reverse current ( ) to flow from ground potential to battery causing excessive power dissipation across the RB diodes in the event of reverse polarity. Hence a reverse polarity protection diode is recommended GND a) HSx ...
