Texas Instruments  BQ24103EVM

The Texas Instruments bq24103EVM is the evaluation module (EVM) for the bq24103 Li-Ion charge management IC. The bq24103 is a highly integrated battery charge IC utilizing synchronous switch mode power conversion for efficient and comprehensive charge control of a single or two series cell Li-Ion battery. The EVM is a complete bq24103 based circuit and provides a convenient method to evaluate the operation and performance of the IC.

The EVM is set up at the factory to charge at 1.33A and a 4.2V (single cell) voltage limit. The output limit can be adjusted to charge a battery pack with two series cells by changing a jumper pin.

The EVM development tool includes a tested evalutation module; a user guide (SLUU200) that contains the schematic, bill of materials, component placement, layout and the setup of the EVM; and the bq24103 data sheet.

The only necessities to use the EVM are a power source (16 max) and the battery to be charged.
