TDA3654 Datasheet | NXP Semiconductors

DESCRIPTION TDA3654 TDA3654Q The TDA3654 is a full performance vertical deflection output circuit for direct drive of the deflection coils and can be used for a wide range of 90° and 110° deflection systems. A guard circuit is provided which blanks the picture tube screen in the absence of deflection current. Features - Direct drive to the deflection coils - 90° and 110° deflection system - Internal blanking guard circuit - Internal voltage stabilizer QUICK REFERENCE DATA Output voltage Output current (peak-to-peak) Supply voltage Guard circuit output voltage Operating ambient temperature range Storage temperature THERMAL RESISTANCE From junction to mounting base PACKAGE OUTLINES TDA3654 : 9-lead SIL; plastic power (SOT131) (1).

March 1991 Philips Semiconductors Product specification Vertical deflection and guard circuit (110˚) FUNCTIONAL DESCRIPTION Output stage and protection circuits TDA3654 TDA3654Q The output stage consists of two Darlington configurations in class B arrangement. Each output transistor can deliver 1,5 A maximum and the VCEO is 60 V. Protection of the output stage is such that the operation of the transistors remains well within the SOAR area in all circumstances at the output pin, (pin 5). This is obtained by the cooperation of the thermal protection circuit, the current-voltage detector and the short circuit protection. Special measures in the internal circuit layout give the output transistors extra solidity, this is illustrated in Fig.5 where typical SOAR curves of the lower output transistor are given. The same curves also apply for the...
