bq24730 Datasheet Charger And System Power Selector

Manufacturer: Texas Instruments

Overview: bq24730 www.ti.com SLUS695 – MARCH 2006 ADVANCED MULTI-CHEMISTRY AND MULTI-CELL SYNCHRONOUS SWITCH-MODE CHARGER AND SYSTEM POWER.

General Description

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.
