DESCRIPTION

The TDA8143 is a monolithic integrated circuit

designed to drive the horizontal deflection power

tran-sistor.

The current source characteristic of this device is

adapted to the non-linear current gain behaviour of

the power transistor providing a minimum power

dissipation. The TDA8143 is internally protected

against short circuits and thermal overload.
