The deflection coil is connected between the output amplifiers, which are driven in opposite phase. An external resistor (RM) connected in series with the deflection coil provides internal feedback information. The differential input circuit is voltage driven. The input circuit has been adapted to enable it to be used with the TDA9150, TDA9151B, TDA9160A, TDA9162, TDA8366 and TDA8367 which deliver symmetrical current signals. An external resistor (RCON) connected between the differential input determines the output current through the deflection coil. The relationship between the differential input current and the output current is defined by: Idiff × RCON = Icoil × RM. The output current is adjustable from 0.5 A (p-p) to 3 A (p-p) by varying RM. The maximum input differential voltage is 1.8 V. In the application it is recommended that Vdiff = 1.5 V (typ). This is recommended because of the spread of input current and the spread in the value of RCON.

The principle of operating with two supply voltages (class G) makes it possible to fix the supply voltage VP optimum for the scan voltage and the second supply voltage VFB optimum for the flyback voltage. Using this method, very high efficiency is achieved. handbook, halfpage I drive(pos) 1 I drive(neg) 2 V I(fb) 3 Vp 4 VO(B) 5 The supply voltage VFB is almost totally available as flyback voltage across the coil, this being possible due to the absence of a decoupling capacitor (not necessary, due to the bridge configuration). Built-in protections are: n.c. 6 • thermal protection GND 7 V FB 8 VO(A) 9 • short-circuit protection of the output pins (pins 5 and 9) TDA8351A • short-circuit protection of the output pins to VP. A guard circuit VO(guard) is provided. The guard circuit is activated at the following conditions: VO(guard) 10 • during flyback n.c. 11 n.c. 12 • during short-circuit of the coil and during short-circuit of the output pins (pins 5 and 9) to VP or ground n.c. 13 • during open loop • when the thermal protection is activated. MGC056 This signal can be used for blanking the picture tube screen. The die has been glued to the metal block of the package. If the metal block is not insulated from the heat sink, the heat sink may only be connected directly to pin 7.

The linearity error is measured without S-correction and based on the same measurement principle as performed on the screen. The measuring method is as follows: Divide the output signal I5 - I9 (VRM) into 22 equal parts ranging from 1 to 22 inclusive. Measure the value of two succeeding parts called one block starting with part 2 and 3 (block 1) and ending with part 20 and 21 (block 10). Thus part 1 and 22 are unused. The equations for linearity error for adjacent blocks (LEAB) and linearity error for not adjacent blocks (LENAB) are given below: a max – a min ak – a( k + 1 ) LEAB = --------------------------- ; LENAB = -----------------------------a avg a avg 3. Referenced to VP. 4.

SOLDERING Introduction to soldering through-hole mount packages The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. Soldering by dipping or by solder wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joints for more than 5 seconds. Suitability of through-hole mount IC packages for dipping and wave soldering methods SOLDERING METHOD PACKAGE DIPPING DBS, DIP, HDIP, SDIP, SIL WAVE suitable(1) suitable Note 1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
