The USB interface simplifies connection to a standard USB port or a dedicated charging adapter. On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions, reducing the need for external supervisory components.
Housed in a 24-VFQFN exposed pad package (24-VQFN 4x4 mm per the supplier device package), the part is surface-mount only.
The maximum charge current is 3A, programmable via the constant-current setting. The actual current in the application depends on the input supply capability, the battery impedance, and the thermal budget of the 24-VFQFN package.
