Средства разработки интегральных схем (ИС) управления питанием BQ24160EVM-721

Оценочная плата , BQ24160 2.5А 2 входа, импульсное зарядное устройство литий-ионных батарей

The BQ24160EVM-721 is a evaluation module for bq24160 battery charger device. The device are highly integrated single cell lithium ion battery charger and system power path management devices targeted for space limited, portable applications with high capacity batteries. The single cell charger has dual inputs which allow operation from either a USB port or higher power input supply (that is, AC adapter or wireless charging input) for a versatile solution. The two inputs are fully isolated from each other and are easily selectable using the I2C interface. The power path management allows the bq24160 to power the system from a high efficiency DC to DC converter while simultaneously and independently charging the battery. The charger monitors the battery current at all times and reduces the charge current when the system load requires current above the input current limit. This allows for proper charge termination and timer operation.

• 153mm × 153mm × 1.2mm footprint for entire solution
