8 Detailed Description

8.1 Overview

The BQ25619 device is a highly integrated 1.5-A switch-mode battery charger for single cell Li-Ion and Li-

polymer battery. It includes the input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2),

low-side switching FET (LSFET, Q3), and battery FET (BATFET, Q4), and bootstrap diode for the high-side gate

drive.
