The 24-VFQFN (4x4 mm) package with exposed pad suits space-constrained portable designs where thermal dissipation through the PCB is critical.
2A charge current and fault protection
The constant-current charge profile is programmable via I²C, with a maximum charge current of 2A. The battery regulation voltage is fixed at 4.2V, matching standard single-cell Li-Ion termination. On-chip fault protection covers over-current, over-temperature, and over-voltage conditions, reducing the need for external supervisory circuits.
The maximum supply voltage is 10.5V, covering standard 5V USB and 9V wall-adapter inputs without an external pre-regulator.
