The BQ25720EVM and BQ25723EVM evaluation modules (EVM) are SMBus or I
boost charger. The input voltage range is from 3.5 V to 26 V, with a programmable output of 1-4 cells and a
charge output current range of 64 mA to 8.128 A. This EVM does not include the EV2400 interface device; the
EV2400 must be ordered separately to evaluate the BQ2572x EVM.
