Using “smart” power MOSFETS
good efficient heatsink will be required for the power device(s). In this way it would be
possible to easily build a high-quality 20-Amp (or higher) power current sink.
8.3 Using “smart” power MOSFETS
In creating power current sources, there are some additional power MOS devices to
consider using. It is worth noting that some manufacturers have introduced DMOS
power devices that have integrated some of the techniques shown in the proceeding
circuits on-chip, for the purposes of either current-monitoring or current-limiting and
device protection. Manufacturers making on-chip current-sensing DMOS power
devices include International ...
