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 The current source characteristic of this device is adapted to the on-linear current gain behaviour of the power transistor providing a minimum power dissipation. The TDA8140 is internally protected against short circuit and thermal overload. POWERDIP (8 + 8) (Plastic Package) ORDER CODE : TDA8140 DESCRIPTION The TDA 8140 is a monolithic integrated circuit designed to drive the horizontal deflection power transistor.

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) (in standard applications pin 6 must be left unconnected). 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). mon Ground 7 8 9-16 Control Input...
