Intersil announced a new single-cell battery charger for low current applications that use low-capacity Li-ion or Li-polymer battery cells. The ISL6298 provides high-accuracy charge current regulation at low current and incorporates the pass-element, current sense function, reverse blocking diode function and self-termination timer.

The charge current is trimmed to have better than 10 percent accuracy at 250mA and is programmable up to 450mA. Charge voltage is regulated at 4.2V +/-1 percent. The ISL6298 also provides basic termination capability, temperature protection and a built-in safety timer.

Additional features include a negative temperature coefficient (NTC) thermistor interface for monitoring the ambient temperature and the ability to disable the time limit of the fast charge.

The ISL6298 is available now in standard lead finish and Pb-free, in either a 16-lead thermally-enhanced 4 mm X 4 mm QFN package or a 3 mm X 3 mm DFN package. The suggested price in 10,000 unit quantities is $0.95 for each IC.
