Protection The output stages are protected against: I idc I defl 4.
The internal guard circuit will not be activated, if the input signals on pins 1 and 2 delivered from the driver circuit are rda4866 of range or at short-circuit of the coil pins 4 and 6. Voltages refer to pin 5 GND.
Stress above one or more of the limiting values may cause permanent damage to the device. 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. 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. 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 resulting from such improper use or sale.
Maximum output currents I4 and I6 are limited by current protection.
Publication thereof does not convey nor imply any license under patent- or other industrial or intellectual property rights. The circuit provides a high CMRR current driven differential input. A layer of silicon grease between the mounting base and the heatsink optimizes thermal resistance. Any difference of this comparison leads to a more or less driver current for the output stages.
The differential input stage delivers the driver signals for the output stages. High bandwidth and excellent transition behaviour is achieved due to the transimpedance principle this circuit works with. Equivalent to discharging a pF capacitor through a 0 Ohm series resistor.
To achieve good noise suppression the following values for Rp are recommended: Due to the feedback loop gain VU loop and internal bondwire resistance Rbo correction factors are required to determine the accurate value of Idefl: Ten uklad to odchylanie V, a na n.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. Deviation of the output slope at a constant input slope.
Plastic or metal protrusions of 0. The feedback input has a current input characteristic which holds the differential voltage between pin 9 and the output pin 4 on zero. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. Zalanczam aplikacje tego scalaka dla zapoznaia sie z nim.
Philips Semiconductors Philippines Inc. The deflection current through the coil Idefl is measured with the resistor Rm which produces a voltage drop Urm of: 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. Therefore the feedback current I9 through Rref is: Due to the absence of a decoupling capacitor the flyback voltage is fully available. 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 relation between the deflection current and the differential input current Iid is: Product specification This data sheet contains final product specifications. Due to the bridge configuration of the two output stages DC-coupling of the deflection coil is achieved.
The guard signal is active HIGH: Box Tda44866Tel.

Driver units with voltage outputs are simply applicable as well tda8466.
Calculated values VP 8. Ten rezystor jest bezpiecznikiem. The total contact time of successive solder waves must not exceed 5 s. 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.
