Product details

Single-cell Li-ion fuel gauge with HDQ

It communicates over a single-wire HDQ interface, keeping the pin count low on a 10-VSON (3x4 mm) package.

10-VSON exposed-pad — layout and thermal path

The 10-VFDFN exposed pad (10-VSON) package requires a thermal land pattern on the PCB that matches the pad dimensions for heat sinking. The exposed paddle is the primary thermal path for the monitor during high-rate charge/discharge cycles. The 3x4 mm footprint fits tight battery-pack layouts.

Temperature grade — consumer portable gear

It is not specified for automotive under-hood or industrial extended-temperature environments.

Frequently asked questions

What is the difference between BQ27000DRKR and BQ27000DRKRG4?

The suffix G4 typically indicates a lead-free (RoHS-compliant) finish compared to an earlier non-G4 variant. The BQ27000DRKRG4 is the lead-free version.

What interface does BQ27000DRKRG4 use?

The BQ27000DRKRG4 uses the single-wire HDQ interface for data communication with a host controller.
