ISL6294AEVAL1Z Evaluation Board
Application Manual
Description
The ISL6294AEVAL1Z is an evaluation tool for the
ISL6294A single-cell Li-ion battery charger. The evaluation
tool provides a complete evaluation platform addressing all
data sheet specifications and functionality. The jumpers on
the board facilitate the programming of the charge current,
different charging conditions, and can be used to make other
necessary connections, such as current measurement.
The ISL6294A is a fully integrated single-cell Li-ion battery
charger. The ISL6294A accepts input voltages ranging from
4.5V up to 28V. Due to the high voltage capability, the
components associated with the cradle input circuit on the
evaluation board are good for a 28V supply.
The components assembled in the center square constitute
a complete charger, indicating the space saving advantage
of the typical ISL6294A installation in space-limited
applications.
