Application Note



Reverse Polarity Protection for ECU (PROFET BTSxxx,
Microcontroller C16x, TLE 426x)



This application note deals with an active reverse polarity protection of an Electronic Control
Unit, a combination of microcontroller, voltage regulator and power switch as it is used in the
automotive industry. The reverse polarity protection is assured by external resistors. The
dimension of the resistors are described by formulas.
