A confirmation request about ULN2003BPWR Ic-Vcesat properties.

Dear,All

I have a confirmation request about Ic-Vcesat properties from customer.

Customer examines ULN2003BPWR in a substitute of TD62503FG used in TOSHIBA now.
Customer identifies Ic-Vcesat properties of TI product ULN2003BPWR.
So, they do not understand the characteristics less than 10mA from the graph of the data sheet (Figure 1,5）.


Would you please send me a document understanding characteristics less than 10mA?

Best Regards,

Haruta

    Hello Haruta-san,

    Are you looking for more accurate data points below Ic = 10mA for the Vce vs Ic curves? The the following would be typical values:

    0mA:  Vce(sat) ~= 0.6V

    5mA: Vce(sat) ~= 0.7V 

    10mA: Vce(sat) ~= 0.725V

    After about 5mA the data becomes more linear. 

    Best,
    Michael

    Hello,Michael

    Thank you for your reply.

    I have some questions.
    Is the answer level from you an answer to Figure 1 of datasheet?
    So, which is numerical value of Iin = 250uA or 350uA or 500uA ?
    Is it all values?
    If the above is Figure 1, do you have data less than 10mA of Figure 5?

    Best Regards,
    Haruta

    Hello Haruta-san,

    Yes, the values from the previous post were for Figure 1.
    To be more specific about the values from Figure 1, they are approximately as follows:

    0mA:  Vce(sat) ~= 0.57V (250uA), 0.60 (350uA), 0.62 (500uA)
    5mA: Vce(sat) ~= 0.7V (applies to all 3 curves)
    10mA: Vce(sat) ~= 0.725V (applies to all 3 curves)

    As for Figure 5, there are no data points that fall below 10mA, are you referring to Figure 2?
    The values for figure 2 are approximately as follows:

    0mA:  Vce(sat) ~= 0.57V (250uA), 0.60 (350uA), 0.62 (500uA) (same as Figure 1)
    5mA: Vce(sat) ~= 0.66V (applies to all 3 curves)
    10mA: Vce(sat) ~= 0.70V (applies to all 3 curves)

    Best Regards,
    Michael
