Internally, a bridge rectifier provides a
polarity-insensitive DC termination for DSL loop
sealing current. The IC includes an electronic inductor,
break-over and latch circuits, current limit and excess
power protection. A sealing current detect output
provides the means to monitor the loop for the
presence of sealing current in the loop.
The CPC1466 is manufactured in Clare’s high voltage
BCDMOS process that is used extensively in
telephony applications worldwide.
