Frequently Asked Questions
What battery chemistry does the L6924D support?
The L6924D is designed for single-cell Li-ion and Li-polymer batteries, providing the constant-current and constant-voltage (CC/CV) charging profile required by these chemistries with adjustable termination voltage.
Is the charge current adjustable on the L6924D?
Yes, the charge current is set by an external resistor or programming pin, allowing designers to optimize charge time and thermal dissipation for battery capacities typically ranging from tens of mAh to several hundred mAh.
What package does the L6924D use?
It is available in a 16-pin VFQFPN package measuring 3x3mm, which provides a small PCB footprint with exposed pad thermal dissipation suitable for compact, thermally managed charger designs.
Does the L6924D include battery protection features?
The L6924D integrates safety timers and thermal regulation circuitry that automatically reduce or terminate charging when the die temperature exceeds safe limits, protecting both the IC and the connected battery cell.
What input voltage source is compatible with the L6924D?
It is designed to operate from USB or adapter input sources typically in the 5V range, making it directly compatible with USB-powered charging docks and wall adapters commonly used in portable consumer electronics.
