How to reduce the zero current offset reading from one of the channel of STPM33?

How to reduce the zero current offset reading from one of the channel of STPM33?Hi, I am using STPM33 for energy monitering. I have 2 STPM33 in my design and hence there are 4 current sense channels where I use shunt resistors for sensing. The proble...

Is there are thermal simulation for VNH3SP30 available in TwisterSIM, or a guideline or whitepaper how to fit a heatsink for the device?

I used e-Design to get a AC-DC converter ref design. I used the L6566BH. The circuit does not start when AC is applied.

How can i calculate the inductor L if i don't use PWM dimming? So, if DIM is connected to VIN

Please, could you help me to know the Junction Temperature (Min) for this part number "STPS30L30DJF-TR" because ST mentioned only the Junction Temperature (Max) in the datasheet?

About the feedforward control calculation problem in 5.2 (FF_VqdffComputation)

The feedforward control block diagram in the official data is as follows: However, the calculation result in FF_VqdffComputation is different, taking ΔUq as an example.ΔUq = (Ke + Ld*Id)*2*pi*p*fr + UqThe code in FF_VqdffComputation is as follows:/*q...

L7985A with lower quiescent current.

I'm searching for a pin to pin replacement for the L7985A with same pinout, same (or better) characteristics, with a lower quiescent current. Any help will be very appreciated. Thanks.

Regarding shunt resistor value in STPM10 mettering device.

Hello. I try tu adjust the value of shunt resistor in STPM10 electronic circuit.First I placed one 0.5mOhm resistor value, and I watched that 40W lamps meassurement is not very exact. Maybe I should to increase this value. But I have read that maxim...
