Part Number: LM26LV
Other Parts Discussed in Thread: TMP390

Hello,

I have a question about LM26LV.

My customer wants to order "LM26LVCISD-042/NOPB" and "LM26LVCISD-045/NOPB".

I checked LM26LV "Order Now" Page, but there are not above part numbers.

Can we order them?

Best Regards,

Kaede Kudo

    Dear Kaede Kudo -
    These are not valid orderable part numbers you are looking for. I checked the datasheet, ti.com and our internal backend to make sure.
    We have never made or offered -042 or -045 variants of the device, so the answer in this case is no, these are not available to order, because they have never existed. Hope that clears up any confusion - let us know how we can assist further if needed.

    Hello Kaede,

    We have just released the TMP390 in which the customer can use resistors to define the threshold settings. The TMP390 has the same operating voltage range and has much lower quiescent current than the LM26LV. Also as can be seen it is a lower cost device compared to the LM26LV, which may be of very much interest to your customer.

    Dear Josh,

    Thank you for your comment.

    ・My customers want the LM26LV preset at 42 °C and 45 °C respectively.
    ・The following is described in D / S.
    - The temperature trip point (TTRIP) can be preset at the factory to any temperature in the range of 0 °C to 150 °C in 1 °C increments
    ・I understand that the end of the part number indicates the preset temperature.
    - LM26LVCISD-100.  The trip point is 100C.

    So I thought I can order the following part numbers.
    - LM26LVCISD-42
    - LM26LVCISD-45

    ・ Is my understanding wrong?
    ・ Does it mean that LM26LV preset at 42 °C and 45 ° C is not provided?
    ・ Is there a way to get the LM26LV preset to 42 ° C and 45 ° C respectively?

    Best Regards,
    Kaede Kudo

    Thank you for your information.
    I will check the D/S for the TMP390.
    I checked the product folder and Status is PREVIEW. When will it be released?

    Dear Kaede Kudo -
    the -42 and -45 variants are not valid part numbers, as i previously explained - I think best course of action here for your customer would be to follow Amit's direction on the TMP390 (if the timing of release is working for them) and/or work with your local TI-J sales contact to bring the business case for these desired variants in as a request.
