Overview

The TIDA-00587 reference design is a charger that has been designed as a booster pack to fit on the TI Launchpad development boards. The use of this this board for development will reduce the time spent in design and test of the bq24250 charger IC. You can charger your battery and using the on board electronic load you can discharge your battery. This will allow you to do cycle testing to measure your batteries performance and capabilities when charging with the bq24250 charger.

Features
  • Booster pack charger designed to fit Launchpad development boards
  • On board 1A electronic load
  • Two board mux to allow stacking two charger booster pack boards
  • Voltage ADC, Current ADC and Temperature ADC for monitoring the battery pack

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
