ISL9214AEVAL1Z Evaluation Board Application
Manual
Description
The ISL9214AEVAL1Z is an evaluation tool for the
ISL9214A 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 and the different charging conditions
and can be used to make other necessary connections,
such as current measurement.
The ISL9214A is a dual input, fully integrated single-cell
Li-ion battery charger. The ISL9214A charger accepts
two input sources: one from a USB port and the other
from a desktop cradle. Both inputs accept 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 ISL9214A installation in
space-limited applications.
Features
