3. The accuracy includes all errors except the programming resistance tolerance. The actual charge current may be affected by the thermal
foldback function if the thermal dissipation capability is not enough or by the on resistance of the power MOSFET if the charger input voltage is
too close to the output voltage.
4. Guaranteed by design, not a tested parameter.
