I know that the STPMIC1C is the "custom" version of this PMIC. And long term, we may choose to use that version. But, due to availability, we want to create our reference design with the STPMIC1E which we can acquire ~300 parts for our prototype bu...
To validate the drive L6474PD I was reading the status through getStatus command but the drive is responding with FFFF. I am not understanding to validate the drive through SPI.
Hello, after reading the data sheet, it's not clear to me if one can synchronize the RHRPMPOL01 to an FPGA pin. Basically the behaviour in slave mode is not described when no sync clock is present (which would be the case on initial power on). In an ...
We specifically use the SiC device SCTH90N65G2V-7.
Hi, I am quoting from a previous question posted on this forum but hasn't been answered. I wanted an answer to the exact same question:I am using the STEVAL-SPIN3201 board to control a BLDC motor.I want to implement a position controller, so I need t...
Hello experts.Question about connecting L4985 to 3 phases.Can I connect like the picture?Will there be any additional recommendations.
We have a Li-ion battery connected to to a charger and to the STC3115.the BATD pin controls the charger Enable/Disable pin , in order to stop the charging while powering up with charger connected.if the battery is empty and we connect the charger, th...
I use ST1S40 to power the microcontroller and SIM800C modem. Microcontroller uses 3.3V after LDO. The modem is powered on by the PWR_MODEM_ON signal and VT3-> VT2. Yellow line - power supply voltage + SIM_VBAT. Blue line + 3V8 after ST1S40.Sometimes ...
