Additional power is dissipated by the integrated R
estimation of overall power dissipation
For reverse battery voltages up to V
connected to signal ground. This can be achieved e.g. by using a small signal diode D
in parallel to the input switch or by using a small signal MOSFET driver. For reverse
battery voltages higher then V
reverse battery voltages higher then V
about 80mA.
Note: No protection mechanism is active during reverse polarity. The IC logic is not
