4 / 38 page Device description L6924U 4/38 1 Device description The L6924U is a fully monolithic battery charger that safely charges single-cell Li-Ion/Polymer battery from either USB power source or AC adapter. In USB mode, the L6924U supports both low power and high power mode. Alternatively the device can charge from AC wall adapter. The ideal solution for space-limited portable products is produced in BCD6 technology and integrates the power MOSFET, reverse blocking diode, sense resistor and thermal protection into a compact VFQFPN16 package. When an external voltage regulated adapter or USB port is used, the L6924U works in linear mode, and charges the battery in a constant current constant voltage (CC/CV) profile. Moreover, when a current-limited adapter is used, the device can operate in quasi-pulse mode, dramatically reducing the power dissipation. Regardless of the charging approach, a closed loop thermal control avoids device overheating. The device has an operating input voltage ranging from 2.5 V to 12 V and it allows the user to program many parameters, such as fast-charge current, end-of- charge current threshold, and charge timer. The L6924U offers two open collector outputs for diagnostic purposes, which can be used to either drive two external LEDs or communicate with a host microcontroller. Finally, the L6924U also provides other features like gas gauge function, check for battery presence, and monitoring and protecting the battery from unsafe thermal conditions. Figure 2.
