Reverse Polarity Protection
TLE42694 is self protected against reverse polarity faults and allows negative supply voltage. External reverse
polarity diode is not needed. However, the absolute maximum ratings of the device as specified in “Absolute
Maximum Ratings” on Page 9 must be kept.
The reverse voltage causes several small currents to flow into the IC hence increasing its junction temperature.
As the thermal shut down circuitry does not work in the reverse polarity condition, designers have to consider this
in their thermal design.
