Управление питанием от батарей BQ25892RTWT

Зарядное устройство для 1-элементной литий-ионной , Li-Pol батареи, 14В вход, 4.6В/5А зарядка

The BQ25892RTWT is a highly integrated 5A switch-mode Battery Charge Management and System Power Path Management Device for single cell Li-ion and Li-polymer battery. It supports high input voltage fast charging. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I²C serial interface with charging and system settings makes the device a truly flexible solution. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. It also integrates Input Current Optimizer (ICO) and Resistance Compensation (IRCOMP) to deliver maximum charging power to battery. The device supports a wide range of input sources, including standard USB host port, USB charging port and USB compliant adjustable high voltage adapter. To support fast charging using adjustable high voltage adapter.
