VN7004SLH 4-layer board design example on datasheet
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...
LTSPICE model of STL210N4F7AG for Thermal modelling not working
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...
Output current limit for RHFL6000A
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...
power output is like AC in stpm34
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?
Resolved! STBC15 wiring of open drain output pins
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 ...
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...
