The Evaluation Kit supports the 34676, which is a dual 28V input voltage and fully-integrated single cell Li-Ion battery charger, targeting smart handheld applications. One of the inputs is optimized for charging with a USB port, and the second is optimized for an AC/DC adapter power source. The charger has two 28V power devices, that eliminate the need for any external power source selection and input over-voltage protection circuitry. Each of the power devices independently controls the charge current from the input, and performs as an independent charger. Only one of the two chargers operate at a time.
The AC charger current and the USB charger current are programmable, up to 1.2A and 400mA, respectively. The EOC current of both chargers is the same, and programmable by an external resistor. The 4.85V regulator can be used to power a sub-system directly.
