BQ24035RHLR

Product Summary

The BQ24035RHLR device is a highly integrated Li-ion linear charger and system power-path management device targeted at space-limited port able application. The BQ24035RHLR offers integrated USB-port and DC supply (AC adapter), power-path management with autonomous power-source selection, power FET and current sensor, high accuracy current and voltage regulation, charge status, and charge termination, in a single monolithic device. The bqTINY-III power the system while indepen dently 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. This feature also allows for the system to instantaneously turn on from an external power source in the case of a deeply discharged battery pack. The IC design is focused on supplying continuous power to the system when available from the AC, USB, or battery sources.
