Protection Functions
The TLE4242EJ provides embedded protection functions, which are designed to prevent IC destruction under
fault conditions described in the data sheet. Fault conditions are considered as âoutsideâ normal operating
range. Protection functions are neither designed for continuous nor for repetitive operation.
The following protection functions are embedded:
⢠Over temperature protection realized by over temperature switch off (see Figure 5-2)
⢠Over load protection realized by output current limitation and over temperature protection
⢠Integrated reverse polarity protection
