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.
