Texas Instruments LM5109BMAX
LM5109BMAX variants from Texas Instruments
LM5109BMAX Overview
What changes between part numbers, and what to check before you lock the BOM — Gate Drivers.
Key Features
- Footprint / package: 8-SOIC (0.154", 3.90mm 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.
Target Applications
- Gate Drivers — 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 Variants
Compare 2 LM5109BMAX part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| LM5109BMAX | Package: 8-SOIC (0.154", 3.90mm Width) | Mounting Type: Surface Mount | Supply Voltage: 8V ~ 14V | Operating Temperature: -40°C ~ 125°C (TJ) | 8-SOIC (0.154", 3.90mm Width) | Texas Instruments | Active | Compliant | In Stock | |
| LM5109BMAX/NOPB | 2-Ch 100V Half Bridge Gate Driver, 1A, 8V UVLO, SOIC | - | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LM5109BMAX Gate Drivers
Match the footprint first
Packages here: 8-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM5109BMAX, 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 "LM5109BMAX" — include the full suffix (e.g. NOPB). RFQ with reel/tube preference and required date code.
