The charge current is constant and programmable up to 500 mA maximum — that ceiling sets the charge time for a given cell capacity, and the programmable nature lets the BOM engineer match the rate to the thermal budget of the VQFN exposed-pad package.
Maximum supply voltage is 6.5 V.
It is current-production from TI and available through independent distribution.
Yes. The device has a USB interface and accepts input from a USB port or 5V adapter up to 6.5 V. The programmable constant-current charge path is designed for single-cell Li-Ion and Li-Polymer batteries at a 4.2 V termination voltage.
Yes. The battery chemistry is listed as Lithium Ion/Polymer, and the battery pack voltage is 4.2 V, which matches the standard single-cell Li-Polymer termination voltage.
No. It is current-production and suitable for new designs.
