ROHM Semiconductor USA, LLC PMIC - Battery Chargers BD8665GW-E2

The BD8665GW-E2 is a lithium-ion battery charger IC designed for charging 2S batteries from a 5V source, utilizing a boost DC/DC topology. It features an input current accuracy of ±3% and a charging voltage accuracy of ±0.5%. The device supports selectable input currents of 100mA, 500mA, 900mA, and up to 1500mA maximum. The typical charging frequency is 1MHz, with a low input standby current of 71µA and a battery leakage current of 0µA when charging is off. The charger is housed in a compact UCSP75M2 package measuring 2.20mm x 2.20mm x 0.85mm. Key features include constant current/constant voltage (CC/CV) charging, charge control via an enable pin, integrated input detection, and output short circuit protection. It is suitable for various applications, including digital video cameras (DVC), digital still cameras (DSC), and other portable devices powered by lithium batteries.
