BQ24030-Q1 汽车类单片充电和系统电源路径管理 IC (bqTINY)
BQ24030-Q1 描述
The bqTINY™ III series of devices are highly integrated Li-ion linear chargers and system power-path management devices targeted at space-limited portable applications. The bqTINY III series offer integrated USB-port and dc supply (AC adapter), power-path management with autonomous power-source selection, power FETs and current sensors, high accuracy current and voltage regulation, charge status, and charge termination in a single monolithic device.
The bqTINY III series powers the system while independently charging the battery. This feature reduces the charge and discharge cycles on the battery, allows for proper charge termination, and allows the system to run with an absent or defective battery pack
