Overview of error conditions
Reset of ERROR Registers and Disable
The TLE7185E can be reseted by the enable pin ENA. If the ENA pin is pulled to low for a specified minimum time,
the error registers are cleared. During reset (ENA = low) the driver outputs are disabled and the external
MOSFETs are switched off actively. Furthermore, the Short Circuit Detection SCD is deactivated as long as ENA
= low.
During disable (ENA = low) any error is shown. However, the Short circuit detection error is reset (error is cleared)
and can not reoccur as the output stages which drive the external MOSFETs are disabled.
In case of under voltage lockout, the ERR pins deviate from the table above as the charge pump is not active and
the TLE7185E is not biased properly.
