This makes it possible to optimize power consumption supply voltage VP and flyback time flyback voltage VFB. Frequency behaviour of Goi and Gofb: Any difference of this comparison leads to a more or less driver current for the output stages.
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.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. Due to the absence of a decoupling capacitor the flyback voltage is fully available. 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. No liability will be accepted by the publisher for any consequence of its use.
At the feedback input pin 9 a part of Idefl is fed back to the input stage. Zalanczam aplikacje tego scalaka dla zapoznaia sie z nim. To achieve good noise suppression the following values for Rp are recommended: Therefore the feedback current I9 through Rref is: The guard signal is active HIGH: Protection The output stages are protected against: 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.

Exposure to limiting values for tfa4866 periods may affect device reliability. Ten rezystor jest bezpiecznikiem. A layer of silicon grease between the mounting base and the heatsink optimizes thermal resistance.
The differential input stage delivers the driver signals for the output stages. Application information Where application information is given, it is advisory and does not form part of the specification. Stress above one or more of the limiting values may cause permanent damage to the device.
The relation between the deflection current and the differential input current Iid is: 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.
The deflection current can be adjusted up to? Equivalent to discharging a pF capacitor through a 0 Ohm series resistor. The circuit provides a high CMRR current driven differential input. Voltages refer to pin 5 GND. Flyback generator During flyback the flyback generator supplies the output stage A with the flyback voltage. Rua do Rocio5th floor, Suite 51, S?
Calculated tda4686 VP 8. The information presented in this document does not form part of any quotation or contract, is believed to be accurate and reliable and may be changed without notice. The Tsa4866 consists of a differential input stage, two output stages, a flyback generator, a protection circuit for the output stages and a guard circuit.
The deflection current through the coil Idefl is measured with the resistor Rm which produces a voltage drop Urm of: Product specification This data sheet contains final product specifications. The total contact time of successive solder waves must not exceed 5 s. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages yda4866 from such improper use or sale.
Hotel Minsk Business Center, Bld. Driver units with voltage outputs are simply applicable as well e.
TDA, BG-ELECTRONICS TDA
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. Reproduction in whole or in part is prohibited without the prior written consent of the copyright owner. High bandwidth and excellent transition behaviour is achieved due to the transimpedance principle this circuit works with.
Maximum output currents I4 and I6 are limited by current protection.
