9.1 Application Information
The 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 resides on the main board of the system and manages an embedded battery (non-removable) or a up to
14500-mAhr Capacity removable battery pack. To allow for optimal performance in the end application, special
considerations must be taken to ensure minimization of measurement error through proper printed circuit board
(PCB) board layout. Such requirements are detailed in Design Requirements.
