For general usage case of a comparator with integrated reference, I would recommend the TLV3011 and TLV3012 which have a 1.2V integrated reference and open-drain or push-pull output stage. If you ever need higher operating voltage, we have the TLV6703…
Part Number: TLV521 Other Parts Discussed in Thread: TLV7041 , TLV3012 , TLV7031 , TLV3011 , LPV821 , TLV7081 Dear team,
My customer is looking to add a current measurement capability in their devices
The solution should consume about one micro ampere.
It…
Other Parts Discussed in Thread: TLV3011 , TLV3012 Hi all,
I have implemented a TLV3011 comparator as described below
That said, I am a little bit worried about the high current that would flow from Cp capacitor (10µF for the current design but could go…
Hello Idan,
Sorry for the delay.
I recommend evaluating the INA146 for this application. I attached a TINA-TI simulation (TINA-TI can be downloaded from www.ti.com/tina-ti ) that uses the INA146 in a gain of 0.1, which will yield a 5V maximum output if…
Other Parts Discussed in Thread: INA138 , TLV3401 , TLC372 , TLV3701 , TLV3012 , TLV3011 I have a sensor with supply voltage of 4.5 - 20 V cc , and and operating frequency of 1 - 2500 Hz and 100 ohms resistance. This signal we are currently reading (I SUPPLY )is…
Thanks for your advice. Since the automatic detection and switching is rather complicated, I am implementing the system using manual switch over. I am using TLV3012 for battery protection and TPS63000 for DC-DC converter. However I have found another device…
Hi Tim, thanks for your explanation! You can see my schematic attached, if i do not place L3 or L4 the power factor decrease from 0.97 to 0.95, if i totally do not place L3 and L4 the power factor is 0.8. Also if i do not place C2 the power factor decrease…
Paul,
I believe your equations are wrong though I'm unable to trace your logical error in writing them.
When the output of the comparator is low, the output is assumed to be at 0V. The voltage at the non-inverting input is Vref*R2/(R1+R2).
Your second…
