BQ27520YZFT-G4

系统端Impedance Track电量计，具有集成LDO System-Side Impedance Track Fuel Gauge With Integrated LDO

The Texas Instruments bq27520-G4 system-side Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development. The fuel gauge resides on the main board of the system and manages an embedded battery non-removable or a removable battery pack.

The fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity mAh, state-of-charge %, run-time to empty minimum, battery voltage mV, temperature °C, and state of health %.

Battery fuel gauging requires only PACK+ P+, PACK– P–, and optional Thermistor T connections to a removable battery pack or embedded battery circuit. The device uses a 15-ball NanoFree™ DSBGA package in the nominal dimensions of 2610 × 1956 µm with 0.5-mm lead pitch. It is ideal for space-constrained applications.
