Overview of BQ25619RTWR
The BQ25618/619 integrates charge, boost converter and voltage protection in a single device. It offers the industrys 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 6 uA in Ship mode, which conserves battery energy to double the shelf life for the device. BQ25619 is in 4x4 QFN package for easy layout. BQ25618 is in 2.0x2.4mm2 WCSP package for space limited design.
