Reset of error registers and Disable

The TLE7186F can be reset by the enable pin RGS. If the RGS pin is pulled to low for a specified minimum time,

the error registers are cleared. If the error is still existing when the RGS pin is pulled to low, no reset will be

performed and the ERR pin stays low. The only exemption of this behavior is the Over Temperature Prewarning.

Even if the junction temperature is exceeding the over temperature prewarning level, the error signal goes to high

when RGS is pulled low.

Figure 13 describes the timing behavior during error reset:

For more details see description of Error Mode and Normal Mode with Over Temperature Pre-Warning in

Chapter 9.1.
