HORIZONTAL DEFLECTION POWER DRIVER - . . . . 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 SIP9 (Plastic Package) ORDER CODE : TDA8143 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.

Reference Ground for Input Voltage at SENSE INPUT. Capacitor between this terminal and SENSE GROUND determines the current slope d IO/dt during OFF phase. Low level at this input sets the device after a delay time tdr in the standby mode independent from CONTROL INPUT (2nd priority). High level at this input switches the BU508 off, low level switches the BU508 on. A high level at this input switches the BU508 off independent from all other inputs (1st priority).
