TSIxxB1
TYPICAL APPLICATION
PTC
Telecom terminals have a diode bridge for polarity
guard, located at the line interface stage. They
also have above this diode bridge one crowbar
protection device that is mandatory to prevent
atmospheric effects and AC mains disturbances
from damaging the electronic circuitry that follows
the diode bridge.
ST proposes a one chip device that includes both
protection and diode bridge. This is the concept of
the TSIxxB1 devices.
