TDA8175

The TDA8175 is a monolithic integrated circuit in HEPTAWATT package. It is a high efficiency power booster for direct driving of vertical windings of TV yokes. It is intended for use in Color and B&W television sets as well as m monitors and displays.

The TDA8175 has the following features include:(1)power amplifier;(2)flyback generator;(3)automatic pumping compensation;(4)thermal protection;(5)reference voltage.The device incorporates a special preampliflier, the gain of which varies with changes in supply voltage.This function allows perfect compensation of height variations caused by changes in brightness.The thermal protection circuit intervenes when the die temperatures reaches 150°C and turns-off theoutput power device.

The absolute maximum ratings of the TDA8175 are:(1)total power disspation:20W;(2)storage and junction temperature: -40 to +150°C;(3)supply voltage:35V;(4)flyback peak voltage:60V.Stresses exceeding these listed under absolute maximum ratings may induce failure.Exposure to absolute maximum ratings for extended periods may reduce reliability. Functionality at or above these conditions is not implied.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure of the TDA8175 is intolerable (i.e., submersible repeater and artificial satellite).
