BQ27Z Overview

What changes between part numbers, and what to check before you lock the BOM — Battery Management.

Key Features

  • Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
  • 3 distinct suffix patternsExamples: 561YPHR-R2, 561YPHT, 746YAHR. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

  • Battery Management — design-in and field replacement
  • BOM scrub where only the base prefix is known but suffix is TBD
  • Second-source checks when the original MPN is constrained

How to Choose the Right BQ27Z Battery Management

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For BQ27Z, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "BQ27Z" — include the full suffix (e.g. 561YPHR-R2, 561YPHT, 746YAHR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the BQ27Z product family.

BQ27Z is a base / family code from Texas Instruments. You order a full MPN such as BQ27Z561YPHR-R2, BQ27Z561YPHT, BQ27Z746YAHR. The variant table lists 3 orderable lines with different suffixes.
Listed suffix fragments include: 561YPHR-R2, 561YPHT, 746YAHR. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.
Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.
Full manufacturer MPN (not just BQ27Z), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
