Product Information

Description

The bq24741 evaluation module is a complete charger module for evaluating a multi-cell synchronous notebook charge and path selection solution using the bq24741 devices. It is designed to deliver up to 6 A of charge current to Li-ion or Li-polymer applications. The charge current is programmable by external voltage input. The bq24741 has a highly integrated battery charge controller designed to work with external host commands. The battery voltage, charge current, input current limit, and other system parameters are pin programmable. 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 the ac adapter current, allowing monitoring of overall system power.
