CW6302/CW6304数据手册Cellwise中文资料规格书

描述 Description

The CW6302 is a high accuracy linear charger with power management solution for Wearable Devices, Activity Trackers and Smart Watches, and Internet of Things, IoT, Devices using Lithium-based batteries. The Power Path Management Unit provides the dynamic charging control to allow the system to drop the maximum load from DC Input; this feature lets the CW6302 perform the most efficient power management among DC Source, Battery Charging and System Loading. This device features 32 steps of charging current programming, 10mA~150mA, and 4 charging voltage selection, 4.20V/ 4.25V/ 4.30V/ 4.35V. CW6302 is also developed for Wearable Devices and IoT applications, high accurate End-of-Charge at small charging current. The settings of charging behavior and system control are programmed through I2C protocol. The Protections include low battery alarm, over current and over temperature. The CW6302 is available in a compact, Pb-Free and RoHS-compliant DFN10 3x3mm2 Package.
