Tone Ringer Interface with DC/DC Converter
Description
The tone ringer interface with dc/dc converter U4078B is
an integrated circuit realized in bipolar technology, which
allows high efficient power transfer. Galvanic separation
takes place at Pin 5 either with inductive or opto-coupler
mode.
Features
Suitable for the specification:
FTZ, 1TR2 and ETR2
Rectifier bridge
Z-diode
Amplitude detection
Detection of ringing signal i.e.,
sine-, triangle-, or rectangular (tone ringing) signal
High-voltage bipolar technology
Compact surface mount package (SO8)
