MOTOROLA ANALOG IC DEVICE DATA
The MC33341 is a monolithic regulation control circuit that is specifically
designed to close the voltage and current feedback loops in power supply
and battery charger applications. This device features the unique ability to
perform source high–side, load high–side, source low–side and load
low–side current sensing, each with either an internally fixed or externally
adjustable threshold. The various current sensing modes are accomplished
by a means of selectively using the internal differential amplifier, inverting
amplifier, or a direct input path. Positive voltage sensing is performed by an
internal voltage amplifier. The voltage amplifier threshold is internally fixed
and can be externally adjusted in all low–side current sensing applications.
An active high drive output is provided to directly interface with economical
optoisolators for isolated output power systems. This device is available in
8–lead dual–in–line and surface mount packages.
