Product details

Single-cell Li-ion fuel gauge with Impedance Track

The Texas Instruments BQ27546YZFR-G1 is a single-cell lithium-ion battery monitor from the Impedance Track™ series. It reports state-of-charge and voltage via an HDQ or I²C interface, making it a drop-in for portable devices that need accurate fuel gauging without a custom algorithm.

Interface and temperature range

Communication is handled through either HDQ or I²C — both common on MCU and PMIC buses — so the host-side integration is straightforward.

Package and mounting

Housed in a 15-bump DSBGA (15-UFBGA) package, surface-mount only. The 0.5 mm pitch and small footprint suit space-constrained PCB layouts, but the BGA requires a solder-paste stencil and reflow profile — not a hand-solder part.

Frequently asked questions

What interface does BQ27546YZFR-G1 support?

It supports both HDQ and I²C interfaces for host communication.

What is the difference between BQ27546YZFR-G1 and BQ27541?

Both are single-cell Li-ion battery monitors from TI, but the BQ27546 uses the Impedance Track™ algorithm for state-of-charge estimation, while the BQ27541 uses a different gauging method. Pin compatibility should be verified against the respective datasheets.
