BQ27421YZFT-G1D

具有集成感应电阻器的 System-side™ 电量监测计 | 电池电量监测计 9-DSBGA -40 to 85

The Texas Instruments bq27421-G1 fuel gauge is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries. The device requires very little user configuration and system microcontroller firmware development.

The bq27421-G1 fuel gauge uses the patented Impedance TrackTM algorithm for fuel gauging, and provides information such as remaining battery capacity mAh, state-of-charge %, and battery voltage mV.

Battery fuel gauging with the bq27421-G1 fuel gauge requires connections only to PACK+ P+ and PACK– P– for a removable battery pack or embedded battery circuit. The tiny 9-ball, 1.62 mm × 1.58 mm, 0.5-mm pitch NanoFree™ chip scale package DSBGA is ideal for space-constrained applications.
