Description
General part information
BQ25618 Series
The BQ25618/619 integrates charge, boost converter and voltage protection in a single device. It offers the industry’s lowest termination current for switching chargers to charge wearable devices by full battery capacity. The BQ25618/619 best-in-class low quiescent current reduces battery leakage down to 6uA in Ship mode, which conserves battery energy to double the shelf life for the device. The BQ25619 is in a 4mm × 4mm QFN package for easy layout. The BQ25618 is in a 2.0mm × 2.4mm WCSP package for space limited design.
