Part Number: LM60

Tool/software:

Hi,

We have recieved notice 20250226003.1,  for part number LM60CIM3X/NOPB.

You are requested to please share wherther there is change in chip for LM60CIM3X/NOPB as well. And with change in chip there is change in Quiescent Current.

Quiescent Current at 25°C: 110μA (Max/Legacy chip) and 70μA (Max/New chip)

LM60 2.7V, SOT-23 or TO-92 Temperature Sensor datasheet (Rev. G)

Regards,

Ritu

    Hi Ritu,

    Yes, as mentioned in the PCN, there is a design change which affects IQ (improved). The devices affected are shown below:

    Hi,

    Thanks so much for your response. As per datasheet,

    1. There is no change in Temp Range for  LM60CIM3X/NOPB for Legacy and New Chip?

    2. Quiescent Current for LM60CIM3X/NOPB will be at 25°C: 110μA (Max/Legacy chip) and 70μA (Max/New chip)?

    Thanks and Regards,

    Ritu

    Hi Ritu,

    Please see my answer below:

    1. This is correct, mainly because LM60C (legacy) already covered the full temperature range of -40°C to 125°C
    2. For the 110μA (legacy) and 70μA (new chip) spec, yes, the temperature condition is Tj = 25°C. For Tj = min to max temperature, see screenshot below

    Best regards,

    Hi,

    Thanks for your prompt help. It is really helpful.

    There will be a mix of inventory for Legacy and New chip part number?

    Will there be any change in MPN for Legacy and New chip?

    How these will be recognized?

    As per notification, there is no  Anticipated impact on Form, Fit, Function, Quality or Reliability so in future only new chip parts will be available and Legacy chip parts will be obsoleted or both will go side by side in future as well.

    Regards,

    Ritu

    Hi Ritu,

    In the short term, yes, there will be a mix. However, all new builds will be done using the new material and both will be under the same MPN. The best way to recognize the new material vs old would be by checking the assembly site which has changed from TIEMA to TIPI and this will be identifiable from the shipping label as shown below (this is an example):
