RT9519BGQW Datasheet PDF - Richtek

●General Description

●The RT9519B is an integrated single cell Li-ion battery charger with Auto Power Path Management (APPM). No

●external MOSFETs are required. The RT9519B enters sleep mode when power is removed. Charging tasks are

●optimized by using a control algorithm to vary the charge rate, including pre-charge mode, fast charge mode and constant voltage mode.

●Features
