TIEVM-VIENNARECT: Clarification on Overcurrent Protection in TIEVM-VIENNARECT

Vishwa Balaji S — Mon, 12 Oct 2026 12:01:07 GMT

Part Number: TIEVM-VIENNARECT

Hi TI Team,

In the TIEVM-VIENNARECT, when the input phase current exceeds the permitted limit, the system enters protection mode

Could you please clarify:

Is overcurrent detected through separate hardware circuitry/CMPSS and ePWM Trip Zone, or through an ADC-based software fault handler?
Is detection based on an instantaneous current threshold, filtered current, or di/dt?
Is PWM shutdown configured as a one-shot or cycle-by-cycle trip?
Which schematic section or firmware function implements this protection and fault recovery?

Thanks
Vishwa

For TI order# T07003594, Sample from Lot Code: 3043177ML3 leads did not exhibit a continuous solder coating free from defects for a minimum of 95% of the critical area of any individual lead thus failed Solderability test.
Detailed picture provided as below.
please help review and advise if this condition consider fail or accetable.

If fail, please help support with RMA. Thank you.

RE: SN74LVTH245A: Order# T07003594 SN74LVTH245ADW failed solderability test

Liyang Wu — Mon, 12 Oct 2026 11:16:33 GMT

Hi Nikki,

Solderability testing is performed in accordance with the applicable J-STD-002 or MIL-STD-883 standard. The component leads are prepared with the specified flux and then dipped into a solder pot. The solder coverage is subsequently inspected to evaluate the solderability of the leads.

We ordered 1001pcs under TI order# T07003594 and total 2 different lot# received: 3043177ML3, 3043179ML3.
We tested total 2 pcs (1pc of each lot#) and 1pcs with DC2302 Lotcode:3043177ML3 failed testing.
Leads did not exhibit a continuous solder coating free from defects for a minimum of 95% of the critical area of any individual lead thus failed Solderability test.

Please help advise further from your quality team. Thank you.

SN74HC14-Q1: Voltage Applied to Input Pins Before VCC is Active

Part Number: SN74HC14-Q1

Hello team,

If voltage is applied to the input pins while VCC is not yet powered, is there a risk of unexpected current flowing back through the device into the VCC rail?

Hello Aayushi,

As Clemens mentioned, The additional marking is related to the lot traceability, date codes, environment information, etc. according to the data sheet. In this case, the additional marking appears to be related to the date.

Thank You,

RE: TPLD2001-DGS-EVM: Is 25MHz Input Clock Enabled on this EVM?

Emrys Maier — Sun, 11 Oct 2026 21:32:57 GMT

Hi John,

U99 is a location to solder down a TPLD2001 providing minimal distance between the terminations on the board and the device itself.

The schematic connections for U99 are shown in the EVM User's Guide: TPLD2001-DGS-EVM on page 15.

John Westmoreland43 — Wed, 07 Oct 2026 18:50:17 GMT

Part Number: TPLD2001-DGS-EVM

Hello All,

I see the two SMB jacks on the EVM - J7 and J8; 25MHz in and 12.5MHz out - respectively; but there are a lot of non-populated parts in that area of the board; so - is that feature not really enabled at this time? Is there a schematic for this section of the board? I will double-check the PDF's and any app notes but wanted to check.

Thanks,
John W.

RE: SN74LVTH245A: Order# T07003594 SN74LVTH245ADW failed solderability test

Nikki Dengel — Fri, 09 Oct 2026 20:27:22 GMT

Hi Liyang,

How did you test solderability? Can you share the details of the test so that we can determine if this is a quality issue? I need information such as dip method/condition (steam aging, flux type, solder temperature, dwell), sample size, and number of leads/devices rejected so that I can share it with our quality team.

Please ensure that you are following the guidelines and recommendations in AN-2029 Handling and Process Recommendations.

Hi Anjali,

This PCN references the Standard Data Packet to find information about form, fit, and function. I cannot share the Standard Data Packet on e2e because this is a public forum. The PCN should have been sent to you by the team that specifically supports PCNs. You will need to contact them to receive the Standard Data Packet.
