Any difference of this comparison leads to a more or less driver current for the output stages. Zalanczam aplikacje tego scalaka dla zapoznaia sie z nim.

The deflection current can be adjusted up to? Equivalent to discharging a pF capacitor through a 0 Ohm series resistor. This circuit will be activated when flyback pulses are missing, which is the indication of any abnormal operation.

Ten uklad to odchylanie V, a na n. Output stages The two output stages are current driven in opposite phase and operate in combination with the deflection coil in a full bridge configuration. Ten rezystor jest bezpiecznikiem. Rua do Rocio5th floor, Suite 51, S? Guard circuit Rm I 9? The total contact time of successive solder waves must not exceed 5 s. Frequency behaviour of Goi and Gofb: The internal guard circuit will not be activated, if the input signals on pins 1 and 2 delivered from the driver circuit are out of range or at short-circuit of the coil pins 4 and 6.

Protection The output stages are protected against: Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. Publication thereof does not convey nor imply any license under patent- or other industrial or intellectual property rights. Exposure to limiting values for extended periods may affect device reliability. The deflection current through the coil Idefl is measured with the resistor Rm which produces a voltage drop Urm of: Jezeli bedzie sie dalej palil to padl ci scalak.

Application information Where application information is given, it is advisory and does not form part of the specification. Driver units with voltage outputs are simply applicable as well e.

TDA, BG-ELECTRONICS TDA

I idc I defl 4. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. Product specification This data sheet contains final product specifications. Box JohannesburgTel.

These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Calculated values VP 8. The TDA consists of a differential input stage, two output stages, a flyback generator, a protection circuit for the output stages and a guard circuit. The differential input stage has a high CMRR differential current mode input pins 1 and 2 that results in a high electro-magnetic immunity and is especially suitable for driver units with differential e.

The circuit provides a high CMRR current driven tva4866 input. A layer of silicon grease between the mounting base and the heatsink optimizes thermal resistance. The information presented in this document does not form part of any quotation or contract, is believed to be accurate and reliable tda44866 may be changed without notice.

The differential input stage delivers the driver signals for the output stages. Plastic or metal protrusions of 0. Philips Semiconductors Philippines Inc.

Stress above one or more of the limiting values may cause permanent damage to the device. Due to the feedback loop gain VU loop and internal bondwire resistance Rbo correction factors are required to determine the accurate value of Idefl: Voltages refer to pin 5 GND.

Hotel Minsk Business Center, Bld. If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering tfa4866 keep the temperature within the permissible limit. Deviation of the output slope at a constant input slope. Reproduction in whole or in part is prohibited without the prior written consent of the copyright owner.

Due to the absence of a decoupling capacitor the flyback voltage is fully available. To achieve good noise suppression the following values for Rp are recommended: Maximum output currents I4 and I6 are limited by current protection.

The relation between the deflection current and the differential input current Iid is: Therefore the Tea4866 requires no external coupling capacitor e. Therefore the feedback current I9 through Rref is: The feedback input has a current input characteristic which holds the differential voltage between pin 9 and the output pin 4 on zero.

The guard signal is active HIGH: Due to the bridge configuration of the two output stages DC-coupling of the deflection coil is achieved.
