Single-cell Li-Ion charger with 28V input tolerance
It accepts a supply voltage up to 28V, making it suitable for systems that need to survive unregulated adapters or 24V industrial rails without an external pre-regulator. The charge current is programmable up to 1.2A, and the IC includes over-voltage fault protection on the input.
The 28V maximum supply voltage is the headline number for this part. It means you can connect a 24V industrial power supply or a 12V automotive rail directly to the input without a series regulator or a high-voltage buck front end — the charger handles it. The 1.2A maximum charge current is programmable, so you can set a lower current for smaller cells or for thermal management in the DFN package.
That is a 2.5 mm × 1.4 mm body with a thermal pad underneath.
It is ROHS3 compliant.
