Frequently Asked Questions
What battery chemistry is the BQ27505YZGR-J1 designed for?
The BQ27505YZGR-J1 is optimized for single-cell Lithium-Ion and Lithium-Polymer batteries. It uses Texas Instruments' impedance track algorithm to accurately estimate state-of-charge and remaining capacity for these chemistries across varying temperatures and aging conditions.
What package does the BQ27505YZGR-J1 use and what are its dimensions?
The BQ27505YZGR-J1 comes in a 12-ball BGA package (DSBGA/YZG) with a 3x4 grid footprint and 0.4mm pitch, making it highly suitable for space-constrained portable and wearable applications where PCB area is at a premium.
How does the BQ27505YZGR-J1 differ from battery-side fuel gauges?
As a system-side fuel gauge, the BQ27505YZGR-J1 is placed on the main system board rather than inside the battery pack. This simplifies battery pack design and allows use with standard unprotected cells, while still delivering accurate capacity and state-of-health measurements via the impedance track algorithm.
What is the typical supply voltage and communication interface for BQ27505YZGR-J1?
The BQ27505YZGR-J1 operates from the battery voltage (typically 2.5V to 4.5V) and communicates with the host processor via an I2C-compatible HDQ or I2C interface, enabling easy integration with microcontrollers in battery-powered systems.
