Power Supply Battery
Charger Regulation
Control Circuit
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

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
