8.1 Overview
The bq24765 integrates buck switching FETs with 700kHz operation for space-constrained, multi-chemistry
portable applications such as notebook and detachable ultrabook. It supports wide input range of input sources
from 7 V to 24 V, and 1~19.2-V charge voltage setting.
The bq24765 features Dynamic Power Management (DPM) to limit the input power and avoid AC adapter
overloading. During battery charging, as the system power increases, the charging current will reduce to maintain
total input current below adapter rating.
The SMBus controls input current, charge current and charge voltage registers with high resolution, high
accuracy regulation limits.
