CW6301/CW6303数据手册Cellwise中文资料规格书

描述 Description

The CW6301 is a highly integrated, cost effective, high accuracy power management unit which is optimized the unique control sequencing and power requirements for the activity tracker application processors and system. The device integrates power management system with four regulators and high accuracy linear charger for Li-Ion batteries with power path management function. This device features three low-dropout linear regulators with supply current 100mA/ 50mA/ 50mA, and one always-on linear regulator with 5mA output current for RTC usage, along with a complete battery charging solution. The CW6301 is available in a compact, Pb-Free and RoHS-compliant QFN16 3x3mm2 package.
