BQ2577xEVM Evaluation Module
Description
The BQ25770EVM or BQ25773EVM evaluation
module (EVM) is a complete high-power high-
efficiency battery charger using SMBus or I
controlled NVDC dual phase buck boost charge
controller BQ25770 or BQ25773. The input voltage
range is from 3.5 V to 40 V, with a programmable
output of 2–5 cells and a charge current range
of 0 A to 16.3 A. This BQ2577xEVM allows the
users to evaluate the function and performance
of the BQ2577x with step-by-step instructions. The
BQ2577xEVM also serves as a reference design
with complete schematic, layout and Bill of Materials
(BOM).
