Figure 65. Overpower Protection Current Relation to Peak of Rectified Input Line AC voltage
Figure 66. Block Schematic of Overpower Protection Circuit
A 3 bit A/D converter with the peak detector senses the ac
input, and its output is periodically sampled and reset, in
order to follow closely the input voltage variations. The
sample and reset events are given by the output from the ac
line unplug detector. The sensed HV pin voltage peak value
is validated when no HV edges from comparator are present
after last falling edge during two sample clocks. See
Figure 67 for details.
