Part Number: LM2903B Team,
Is it possible to use the same PCB footprint in order to solder SOT-23-THIN 8 (DDF) or WSON 8 (DSG) ?
Do we have example of PCB footprint that could be compatible with both packages?
Sine the dimension do not appear in…
The LMxxx number, including A/AV/B suffixes, indicates different die revisions and electrical characteristics; see p. 1 of the datasheet.
The D/PW/DDF/DGK/DSG/PS/P suffix indicates the package.
The R suffix indicates a large reel (no suffix is tube…
Part Number: BQ41Z90 Hello,
On a 7S design (series FET config), we observe that during the PREDISCHARGE phase the DSG pin actively pre-biases the external gate to 2.8 V above its source. We see the same 2.8 V on the BQ41Z90 EVM, where it is harmless…
Part Number: BQ41Z90EVM
Hello TI team, I am testing the BQ41Z90EVM and have a question about the J30 header for CFETOFF/DFETOFF control. According to the EVM User’s Guide, I expected the J30 pin order to match the guide description. However, on my actual…
Hi Dominik,
Thank you for checking this with the FW and SQM teams. My gauge is using FW 0.02.
I repeated the test with the DSG MOSFET jumper removed, so only the PDSG path could charge PACK+.
Test conditions:
- Predischarge resistor: 4…
Hello Ethan,
We just released the TLV1922 a few months ago...It is the only high voltage (>35V) comparator with internal reference. There are no direct equivalents.
Is this for an actual product? Or for prototyping?
If prototyping, you can use the…

Part Number: BQ40Z80 Other Parts Discussed in Thread: EV2400 , BQSTUDIO Hi
I have designed a custom board for the BQ40Z80 using a 5 or 6s battery configuration. I have successfully validated the parameters using the EVM, however my board will not…
Hello Jonny,
We have three different boards, and the same issues are occurring on all three. I don't think this is a DSG FET gate issue. The DSG FET only conducts when we apply power to the IC PACK pin. That is why the BQ28Z620DRZR EVM board has an…
