Hello Pekka,
I see a few issue.
The low batt detector, IC5B has the input range violated on both inputs. The specified input range is Vcc-1.5V (Vcc-2V at cold). Your V+ supply is 2.8V, which would make the valid input range up to +1.3V at room temp, and…
Part Number: LM8364 Other Parts Discussed in Thread: TPS3703-Q1 , TPS3700 , LM2903 , LMC6772 , UC3844 , TLV3402 , TLV7042 , LMV393 , ATL432 , ATL432LI , TL432 Hi Team,
I would like to try low power consumption comparator to replace LM2903 DR2G, your nice engineer…
Hello Logan,
Simple. You are violating the input voltage range on both inputs. The maximum input voltage is 1.5V below VCC for the LM393 family, or 1.8V in your case.
You need to bring the voltages down below 1.8V, or, use a rail-to-rail input device…
Hello David,
Some suggestions:
LMC6772 (needs pull-up resistor on output)
TLV3702 (does not need pull-up)
I would also recommend placing a 10k resistor in series with the V+ input to limit the current into the pin should there be a fault.
What you…

Hello Quasim,
There are many devices. The TLV7041 is available in the SC-70 package.
We do have SC-70 to DIP adapters available:

Similar items are usually available from distributors (Digikey, SparkFun, Mouser, etc…
Hi Cedric,
Unfortunately we do not have a curve for how the common mode input voltage range varies as a function of temperature. The part however will have a maximum input common mode voltage of Vcc-2V over the temperature range of -25°C to 85°C. …

Hi all,
I have referred the LM393 data sheet. And I am in need of few clarifications;
I am employing LM393 as a comparator in a speed sensor application
Q1. Data sheet mentions…
