Part Number: TLV4021 Hi TI expert
We are now use TLV4021, then, we nned to know the size of the Pocket.
reading from below image in datasheet, the A0 & B0 size is 0.84mm,
we found the real size is over size, It is the bottom size of the pocket. …
Hello Joseph,
If both the comparator and CPU are at 3.3V, then you can drive the input directly. Maybe a 100k pull-down to make sure any turn-on transients don't pull it high.
The older comparators do not have a UVLO (we call POR), they just start…
Part Number: LM393B Other Parts Discussed in Thread: LM339 , TLV4021 , TLV7042 , TLV7041 , TLV7021 , TLV7022 , TLV7081 , LM393LV , LM139 Hi,
My customer uses LM393B as voltage detection.
when there is input power and ambient temperature is at >0C, it works normally…
Hi Chris,
Based on your usage case, I would recommend looking into the TLV3701 and the TLV4021. Both of these parts are specified to perform like your design requires. The TLV4021 has an internal reference of 1.2V and the TLV3701 has no internal reference…
Hello Anthony,
My guess is the "constraint" is because the original designers had to make a compromise between maximum supply voltage, input offset and maximum input range. Adding additional input range would have added more complexity, compromised accuracy…
Part Number: TLV3691 Other Parts Discussed in Thread: TLV4031 , TLV4051 , TLV4021 , TLV4041 , TLV6703 , TLV3011 , TLV3012 Hi team,
My customer is looking for a comparator which support 1.8V to 5.5V Vcc, Vref=1.2V and package is preferred to be DFN1.6*1.6(not…

Unfortunately I don't have anything newer to offer that is auto qualified.
The next generation comparator with reference is our TLV4021 family.
Please check it out and let me know what you think. www.ti.com/.../tlv4021.pdf

Hi Adrian,
For the comparator/reference combo, see the new TLV4021 comparator + reference family.
They have various combinations of reference voltages and input and output options. You would want the "R1" versions for the 1.2V reference and "PP" output…
Hey Shinji,
Consider this circuit using the INA185A1 and TLV4021: https://www.ti.com/lit/an/sboa349/sboa349.pdf . The INA185 does not come in Q100, but it very similar to the INA180A1-Q1 so the design procedure can be used. In order to meet the requirement…
