bq24072/3/4/5/9(T) and bq24230/2 1.5-A Single-Chip Li-Ion
and Li-Polymer Charge Management IC EVM
This user's guide describes the bq24072/3/4/5/9(T) and bq24230/2 (bqTINY-III™) evaluation module
(EVM). The EVM provides a convenient method for evaluating the performance of a charge management
and system power solution for portable applications using the bq24072/3/4/5/9(T) and bq24230/2 product
families. A completely designed and tested module is presented. The charger is designed to deliver up to
1.5 A of continuous current to the system or charger for one-cell Li-ion or Li-polymer applications (see the
data sheet for correct device) using a dc power supply. The charger is programmed from the factory to
deliver 0.9 A of charging current. This EVM was designed as a stand-alone evaluation module, but it also
can be interfaced with the system and host via the connectors and headers.
