3 Description  
The BQ25618E/619E integrates charge and voltage  
protection in a single device. It offers low termination  
current for switching chargers to charge wearable  
devices to full battery capacity. The BQ25618E/  
BQ25619E low quiescent current reduces battery  
leakage down to 7 μA in Ship Mode, which conserves  
battery energy to extend the shelf life for the device.  
The BQ25619E is in a 4 mm x 4 mm QFN package for  
easy layout. The BQ25618E is in a 2.0 mm x 2.4 mm  
WCSP package for space-limited designs.
