Advanced Multi-cell Battery Charger And System Power Selector

  The BQ24730 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 hardware 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. The input Current Sense Amplifier can be enabled with no adapter to sense Battery discharge current. Integrated features such as charger soft start, charge overcurrent protection, and IC temperature monitoring provide a second level of protection, in addition to pack and system protection functions.
