Hi All,I have been stuck for a week with this.7I can read and write to the registers of both L6470 correctly.And I can also send commands properly to L6470 via the SPI from STM32F407 discovery kit.However, when I try to start driving the motor, the m...
When using the chip GIPS30C60-H, sometimes the three-phase bridge switching signal is given but there is no output, regardless of whether the SD/OD pin is set high or not. This chip is used in a motor controller with a 0-270V DC bus supply and input ...
I can't find the max operating voltages of the logic pins. Is it same as Vcc? Thanks.
On p23 Fig 35 of https://www.st.com/resource/en/datasheet/vn7004slh.pdf, Are the big copper areas on the 4-layer PCB around the IC GND or VCC? The figure seems to be GND, but how can GND help dissipate the heat from the ICs if the thermal vias are c...
Hello,I am trying to create the thermal model of Buck boost converter for my 20V application. I found STL210N4F7AG from ST with low Rds_on available on market. I dowloaded the spice model and created a symbol based out of V3lib file. I put it in my m...
Hi All, In this LDO the output current limit can be set by a Rshort resistor from pin 8 to V_in.Is there any formula for the calculation of such a resistor? On the Figure 19 in the datasheet there is a plot showing Short-circuit current vs RSHORT for...
I use stpm34. stpm34 reads voltage and current as rms. but stpm34 read active/reactive power like ac.I think stpm34 should read them like dc. is it right? I wanna dc value of active/reactive power.Could you help me?
Hello, I see there are two open drain output pins on the STBC15: CHGINOK and PG. If I don’t need to read the CHGINOK and PG status, can they either be left floating or connected to ground, without needing to add an external pullup? Please confirm if ...
The datasheet says that LM211D/DT has a temperature of -40 °C, +105 °C and output to negative supply voltage 50VLM311D/DT has a temperature of -0 °C, +70 °C and output to negative supply voltage 40VIs there any differences in performance or electrica...
