+title: Richtek RT9759 Smart Cap Divider Charger
+

+
+description: |
+ The RT9759 is a high efficiency and high charge current charger.
+ The efficiency is up to 97.8% when VBAT = 4.2V, IBAT = 2.5A and the maximum
+ charge current is up to 8A. The device integrates smart cap divider topology
+ with dual phase charge pump core. The ADCs provide input and output voltage,
+ current and temperature information to monitor the whole charging process.
+
+ Datasheet is available at
+ https://www.richtek.com/assets/product_file/RT9759/DS9759-02.pdf
