What is the difference between the LM211 and LM311
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...
Resolved! TCPP03-M20 using Mosfet driver outputs for logic control
Hello,I'm using TCPP03 for a DRP solution. For my design it would be good to use the Mosfet drivers for controlling a logic input for further power control instead of using Mosfets. Is it possible to use the gatedrivers with the SRC-pins connected to...
steval-L99615C GUI not working
Connected discovery board to COM port. Using Demo bin file, have been able to view data with serial monitor. When I connect using Unicleo GUI 1.25.1.11665, COM port message states successfully opened. Unable to view any other data. Firmware: Expansio...
Resolved! L6924D Battery charger NTC selection
I require assistance with the design of the battery charger schematics involving the L6924D. Referring to the documentation (https://www.st.com/resource/en/datasheet/l6924d.pdf), the pull-up resistor R3 is 1K, and the NTC tuning resistor R9 is 470 oh...
can I use wireless charging IC in a resonant frequency of 13.56HZ?
I want to buy a wireless charging IC like STWBC86JR, but the data sheet says that it should be within the standard frequency of 110kHZ to 205kHZ, so can't I use it with a resonant frequency of 13.56MHz? Is there an IC available on that frequency? Is ...
STSPIN840 OUTX1 and OUTX2 signals
Hi,We have PCB where STSPIN840 is connected to PIC32MK1024MCF100 and DC motors connected to respective OUTX pins. Getting PWM,PH(high),EN(high) when we are checking signals in CRO but OUTX1,OUTX2 both as 3.3v or one 3.3v another 12v sometimes. Accord...
STEVAL-ASTRA1B Low-power
Hi. I am currently evaluating the STEVAL-ASTRA1B as a low-power LoRaWAN-GPS tracker. My goal is to have the device wake up every 10 minutes to send a GPS position.I am however facing some problems getting the current consumption down to the advertise...
Thermal model, PCB guidelines and Heatsink or Mechanical model for STPAK package
Hi, We are planning to use SCTHS300N75G3AG Sic Power MOSFET in our design. For this STPAK package MOSFET please provide Thermal model, PCB guidelines and Heatsink or Mechanical model.
SCTHS300N75G3AG Sic POWER MOSFET Rds(ON)
Hi all, In SCTHS300N75G3AG Sic power MOSFET data sheet mentioned that 8.8mΩ Rds constant over maximum temperature. But in graphs Rds(on) reached to above 1.3mΩ. So, which value we need to consider for power dissipation calculation.
