STMicroelectronics TDA8143
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.| Part No. | TDA8143 |

Reference Ground for Input Voltage at SENSE INPUT. Capacitor between this terminal and SENSE GROUND determines the current slope dIO/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).
