HelloI would like to confirm with you the power on reset behavior of TS334.When I power up the comparator, I see a high level impulse during power on.I guess there is a power on reset behavior of TS334. In the following figure, the blue curve is the ...

HelloCould you share some detail of STM32U585 temperature sensor information?When do the calibration in plant, how to guarantee the junction temperature of the chip? Do you perform the calibration with bare die or with package?How about the linearity...

HelloI use the embedded Op Amp in STM32U585VIT3Q to charge a 47uF capacitor.The input of the Op Amp is connected to the output of DAC. The voltage level is 3V.So you can see when the Op Amp begin to charge the cap, the peak current is quite large.I w...

HelloCould you let us know how the temperature sensor is calibrated in plant?Do you perform the calibration at die level or after packaged?How do you control the junction temperature of the die?Thanks in advance!

HelloThe error is not from the Micro. It is the problem of power supply. As the Micro is not supplied properly, the measurement of the temperature sensor seems appear an error. When I give the right supply, the sensor works normally. it gives the rig...

HelloI do some temperature test based on two Micro. Below 115C, it seems the temperature sensor is quite accurate. But something interesting is when the temperature is higher than 115C, the measured temperature by Micro is totally wrong. It goes to 4...

Hello JWThanks for your reminding. I understand there is temperature difference between die and case. But what I am interesting is the temperature error for junction temperature.If I follow the calibration data in the Micro, what is the temperature d...
