General Description
5.4
Reverse Polarity Protection
The TLE94108EL requires an external reverse polarity protection. During reverse polarity, the free-wheeling
diodes across the half bridge output will begin to conduct, causing an undesired current flow (IRB) from ground
potential to battery and excessive power dissipation across the diodes. As such, a reverse polarity protection
diode is recommended (see Figure 4).
