Texas Instruments BQ20Z
BQ20Z variants from Texas Instruments
BQ20Z Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
BQ20Z is a Texas Instruments order-code family — not a single orderable MPN. This page lists 6 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Fuel Gauge Li-Ion/Li-Pol 20-Pin TSSOP T/R Other listed variants describe: SBS 1.1-compliant gas gauge enabled with Impedance Track™ technology 20-TSSOP -40 to 85; SBS 1.1 compliant gas gauge enabled with Impedance Track™; technology for use with the bq29312A 38-TSSOP -40 to 85.
Across listed variants, watch these parameters: packages: 20-TSSOP (0.173", 4.40mm Width).
Suffix examples in this family: 40PWR-R1, 70PWR-V150, 80ADBTR-V110, 80DBTR-V102, 80DBTR-V110, 40PWR. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: BQ20Z40PWR-R1, BQ20Z70PWR-V150, BQ20Z80ADBTR-V110, BQ20Z80DBTR-V102, BQ20Z80DBTR-V110, BQ20Z40PWR.
Key Features
- Footprint / package: 20-TSSOP (0.173", 4.40mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 6 distinct suffix patternsExamples: 40PWR-R1, 70PWR-V150, 80ADBTR-V110, 80DBTR-V102, 80DBTR-V110 (+1 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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

Ordering Code Differences
How suffixes on BQ20Z map to package, grade, and reel options.
BQ20Z uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 40PWR-R1, 70PWR-V150, 80ADBTR-V110, 80DBTR-V102, 80DBTR-V110, 40PWR.
Full MPN examples: BQ20Z40PWR-R1, BQ20Z70PWR-V150, BQ20Z80ADBTR-V110, BQ20Z80DBTR-V102, BQ20Z80DBTR-V110.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right BQ20Z Microcontrollers
Match the footprint first
Packages here: 20-TSSOP (0.173", 4.40mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For BQ20Z, 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 "BQ20Z" — include the full suffix (e.g. 40PWR-R1, 70PWR-V150, 80ADBTR-V110). RFQ with reel/tube preference and required date code.
