Product Summary

The ACT3780QY-T is an activepath battery charger. The ACT3780QY-T is a complete battery charging and management solution for one cell Lithium-Ion or Lithium- Polymer battery. The ACT3780QY-T incorporates the ActivePath architecture which automatically selects the best available input supply for the system. The ACT3780QY-T charger is a complete, thermally regulated, stand-alone single cell linear Li+ charger that integrates an internal power 12V MOSFET. The battery regulation voltage is ±0.5% accurate, and is factory programmed from 4.2V (other voltages available upon request). The ACT3780QY-T is available in an thermally enhanced 4mm x 4mm Thin-QFN and 3.5mm × 4.5mm Thin- DFN 20-pin packages. Applications are (1)Personal Navigation Devices; (2)Smart Mobile Phones; (3)Blue-Tooth Devices; (4)Portable Media Players; (5)Portable Devices.
