MCP7383XRD-PPM MCP7383X Li-Ion System Power Path Management Reference Design

Portable electronics has played an important role in modern era. Due to the natural characteristics of Li-Ion / Li-Polymer batteries, they are the most popular power sources for mobile devices. However, extra care in design is always important to implement Li-Ion / Li-Polymer batteries. System Power Path Management allows end-users to charge their batteries without interruption.

This reference design is developed to assist product designers in reducing product design cycle and time by utilizing Microchip’s favorite stand-alone Li-Ion battery charge management controllers with system power path management.

  • Load sharing system power path management that support charging single cell Li-Ion battery and system load at the same time without affecting charging algorithm of Microchip’s stand-alone charge management controllers.
  • The system load is supported by Li-Ion battery when input power source is removed
  • Blue LED indicates charge status
  • Additional Red LED to indicate Power-Good (PG) and Green LED to indicate charge complete (Available from MCP73833)
  • Dip Switch to select programmable fast charge current between1000 mA (H) and 50 mA (L) for MCP73833 and 400 mA (H) and 25 mA (L) for MCP73832
  • Available THERM pin on the MCP73833 for temperature monitoring with a thermistor. It is disabled by default and can be enabled to use with NTC thermistor
