Power Supply Battery Charger Regulation Control Circuit

Favorite

Overview

The MC33341 is a monolithic regulation control circuit that isspecifically designed to close the voltage and current feedback loops inpower supply and battery charger applications. This device features theunique ability to perform source high–side, load high–side, sourcelow–side and load low–side current sensing, each with either aninternally 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.

  • Differential Amplifier for High-Side Source and Load Current Sensing
  • Inverting Amplifier for Source Return Low-Side Current Sensing
  • Non-Inverting Input Path for Load Low-Side Current Sensing
  • Fixed or Adjustable Current Threshold in All Current Sensing Modes
  • Positive Voltage Sensing in All Current Sensing Modes
  • Fixed Voltage Threshold in All Current Sensing Modes
  • Adjustable Voltage Threshold in All Low-Side Current Sensing Modes
  • Output Driver Directly Interfaces with Economical Optoisolators
  • Operating Voltage Range of 2.3V to 16V
  • Pb-Free Packages are Available
