Block Description and Electrical Characteristics
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 U_ST output capacitor will be discharged
and this will cause U_ST 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 U_ST.
After power up when the first watchdog edges at WD1 a WD2 are detected the Enable
output is switched into High state.
