Description

The bqTINY^TM-III series of devices are highly inte-grated Li-ion linear chargers and system power-pathmanagement devices targeted at space-limited port-able applications. The bqTINY-III series offer inte-grated USB-port and DC supply (AC adapter),power-path management with autonomouspower-source selection, power FETs and current sensors, high accuracy current and voltage regu-lation, charge status, and charge termination, in asingle monolithic device.

The bqTINY-III powers the system while indepen-dently charging the battery. BQ24032ARHLR feature reduces thecharge and discharge cycles on the battery, allowsfor proper charge termination and allows the systemto run with an absent or defective battery pack. BQ24032ARHLR feature also allows for the system to instantaneouslyturn on from an external power source in the case ofa deeply discharged battery pack. The IC design isfocused on supplying continuous power to the systemwhen available from the AC, USB, or battery sources.
