TDA 16846

TDA 16846-2

several protection functions: VCC over- and undervoltage, mains undervoltage, current

limiting and 2 free usable fault comparators. Regulation can be done by using the

internal error amplifier or an opto coupler feedback (additional input). The output driver

is ideally suited for driving a power MOSFET. Fixed frequency and synchronized

operation are also possible.

The TDA 16846-2 is suited for TV-, VCR- sets, SAT receivers and other sets for

consumer electronics. It also can be used in PC monitors.

The TDA 16847-2 is identical with TDA 16846-2 but has an additional power

measurement output (pin 8) which can be used as a Temporary High Power Circuit.
