Description
General part information
BQ24721C Series
The bq24721 is a high efficiency synchronous battery pack charger with high level of integration for portable applications. This device implements a high performance analog front-end that interfaces to the system power management micro-controller through a simplified SBS-like SMBus interface.
The dynamic power management (DPM) function modifies the charge current depending on system load conditions, avoiding ac adapter overload.
High accuracy current sense amplifiers enable accurate measurement of either the charge current or the ac adapter current, allowing termination of nonsmart packs and monitoring of overall system power.
