5.3.2
The power supply Voltage V
shows the error flag signalling during an undervoltage and overvoltage situation where as
hysteresis concept implemented during undervoltage and overvoltage.
Under Voltage
If the supply voltage V
the Error Flags remain high (no error). If V
are restarted.
Over Voltage
If the supply voltage V
Error Flags are set. The error is not latched, i.e. if V
power stages are restarted and the Error Flags are reset.
