Texas Instruments BQ25176JEVM Evaluation Module

Texas Instruments BQ25176JEVM Evaluation Module is designed to evaluate and test the various operating modes of the BQ25176J 800mA linear battery charger IC. This evaluation module includes BQ25176J IC and LDO TPS7B8133. The BQ25176J charger is an integrated 800mA linear charger for 1-Cell Li-Ion, Li-Polymer, and LiFePO4 batteries targeted at space-limited portable applications. This evaluation module operates at 5V input voltage, 3.5V to 4.4V output voltage range, and 60mA to 750mA output current range. The BQ25176JEVM module is ideal for true wireless headsets, wearable accessories and smart bands, beauty and grooming, and electric toothbrushes.
