BQ24073 USB 供能的锂离子电池充电器和电源路径管理 IC,4.4V 输出电压

BQ24073 描述

The bq2407x series of devices are integrated Li-ion linear chargers and system power path management devices targeted at space-limited portable applications. The devices operate from either a USB port or AC adapter and support charge currents up to 1.5A. The input voltage range with input overvoltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the bq2407x to meet USB-IF inrush current specification. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing incorrectly configured USB sources. The bq2407x features dynamic power path management (DPPM) that powers the system while simultaneously and independently charging the battery
