4.5

Enable-Output EN

The open collector enable output EN informs the system about any error condition. Any

error except a detected supply under-voltage will set the EN output Low. Of cause for

long under-voltage at the supply line, soon the

UST output capacitor will be discharged

and this will cause

UST under-voltage and therefore EN Low. The time depends on the

load and the output capacitor. The EN is an open collector output. It is short circuit

protected to

UST.

After power up when the first watchdog edges at WD1 a WD2 are detected the Enable

output is switched into High state.
