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.

. CONTROLLED DRIVING OF THE POWER TRANSISTOR DURING TURN ON AND OFF PHASE FOR MINIMUM POWER DISSIPATION AND HIGH RELIABILITY

. HIGH SOURCE AND SINK CURRENT CAPABILITY

. DISCHARGE CURRENT DERIVED FROM PEAK CHARGE CURRENT

. CONTROLLED DISCHARGE TIMING

. DISABLE FUNCTION FOR SUPPLY UNDER VOLTAGE AND NONSYNCHRONOUS OPERATION

. PROTECTION FUNCTION WITH HYSTERESIS FOR OVERTEMPERATURE

. OUTPUT DIODE CLAMPING

. LIMITING OF THE COLLECTOR PEAK CURRENT OF THE DEFLECTION POWER TRANSISTOR DURING TURN ON PERIOD

. SPECIAL REMOTE FUNCTION WITH DELAY TIME TO SWITCH THE OUTPUT ON
