reverse voltage protection of TLE9201 and etc

Open rusefi opened this issue 5 years ago • 1 comments

DonaldBecker says "The v0.3 MRE appears to have a weakness with reverse voltage protection (when the battery is connected in reverse, applying -12V to the +12V circuit).

Specifically unprotected 12V power is supplied to the e-throttle TLE9201 H-bridge chip, several pins of the TLE8888 (BATPA, BATPB) and the main capacitor. These are not rated for negative voltage."
