Product Information

Description

The bq24750/51 evaluation module is a complete charger module for evaluating a multi cell synchronous notebook charge and path selection solution using the bq24750/51 devices. It is designed to deliver up to 6 A of charge current to Li-Ion or Li-Pol applications. The charge current is programmable by external voltage input.

The bq24750/51 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.
