bq24726 Datasheet 1-4 Cell Li+ Battery Smbus Charge Controller

Manufacturer: Texas Instruments

Overview: bq24726 .ti. SLUSA79A – JULY 2010 – REVISED NOVEMBER 2010 1-4 Cell Li+ Battery SMBus Charge Controller with N-Channel Reverse Blocking MOSFET Gate Driver and Advanced Circuit Protection Check for Samples:.

General Description

The bq24726 is a high-efficiency, synchronous battery charger, offering low ponent count for space-constraint, multi-chemistry battery charging applications.

The bq24726 utilize charge pump to drive n-channel RBFET to improve system efficiency.

SMBus controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be programmed by the system power management micro-controller.

Key Features
