Page 7: Introduction
This user’s guide describes the bq24013 (bqTINY ) evaluation module. The EVM provides a convenient method for evaluating the performance of a charge-management solution for portable applications using the bq24013 product family. A complete designed and tested charger is presented. The charger is designed to deliver up to 1.0 A of continuous charge current, but is... -
Page 8: Background
Background 1.1 Background The bqTINY series are highly integrated Li-Ion and Li-Pol linear charge-management devices targeted at space-limited portable applications. In a small package, the bqTINY series offer integrated PowerFET and current sensor, reverse blocking diode, high-accuracy current and voltage regulation, charge status, and charge termination. -
