bq24070/1 1.5-A Single-Chip Li-Ion and Li-Pol Charge
Management IC EVM
This user’s guide describes the bq24070/1 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 bq24070/1 product
family. A completly 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 using a dc power supply. The charger is programmed from
the factory to deliver 1 A of charging current.
