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.
L6207 - positive output voltage regardless of input signal
Hello, Sorry if this post has the wrong label/location. I have a problem with L6207 dual bridge motor driver. I am using stm32f031k6 mocrocontroller and L6207 to control two motors. While using the devices on evaluation boards they worked perfectly. ...
Resolved! STUSB4700 - Default 5V on VBUS not present if nothing connected to output connector
Hello,Ive designed a PCB with a STUSB4700QTR as a source following the datasheet ref design. The scope was to use the board as a charger with PD.When I plug a USB C phone on my source connector, the board deliver 2.2A at 9V on VBUS and the phone char...
ADP480120W3 gate resistance
HiDoes anyone know what the internal resistance value of ADP480120W3 module is? Or where could i find this data? The datasheet doesn´t show it.Thanks in advance
