TEXAS INSTRUMENTS BQ24765EVM Evaluation Module, Power Management, Battery Charger, BQ24765
The is a complete charger module for evaluating a multi cell integrated power MOSFETs synchronous notebook charge using the bq24765 device. It is designed to deliver up to 8A of charge current to Li ion or Li pol applications. The charge current is programmable by SBS like SMBus interface. The bq24765 frequency is 700KHz for small inductor. The bq24765 has a highly integrated battery charge controller designed to work with external host commands. The charge voltage, charge current, and input current are programmable via SBS like SMBus interface. The dynamic power management 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.
