TSIxxB1
TERMINAL SET INTERFACE
PROTECTION AND DIODE BRIDGE
MAIN APPLICATION
Telecom equipment requiring combined
protection against transient overvoltages and
rectification by diode bridge :
s Telephone set
s Base station for cordless set
s Fax machine
s Modem
s Caller Id equipment
s Set top box
DESCRIPTION
The TSIxxB1 provides the diode bridge and the
crowbar protection function that can be found in
most of telecom terminal equipment.
Integrated monolithically within a SO-8 package,
this ASD™ device allows space saving on the
board and greater reliability.
