Product Summary

The BQ24085DRCR is a 750 mA single-chip Li-Ion/Li-Pol charge management IC with thermal regulation. The BQ24085DRCR offers a variety of safety features and functional options, while still implementing a complete charging system in a small package. The BQ24085DRCR automatically restarts the charge if the battery voltage falls below an internal threshold; sleep mode is set when the external input supply is removed. The applications of it are PDA, MP3 Players, Digital Cameras, Internet Appliances and Handheld Devices.
