STC3100 Current register nonsense values

Hi, I am having the same issue as this previous forum post, but the question was never answered.  Voltage and temperature sense give expected readings. REG_VOLTAGE_LOW: 29; REG_VOLTAGE_HIGH:6 --- VOLTAGE: 3818mVREG_TEMPERATURE_LOW: 186; REG_TEMPERATU...

Resolved! PM8805TR output voltage

Hello everyone    I'm working on a student project with an STM35H563RIT6 and a Power over Ethernet (PoE) supply. I'm currently validating my design, but, reading the datasheet of the PM8805TR to do PoE, I just see the output current (max 2A) but no v...

Resolved! STP16CPC26 SDO output stuck low

This is our first board design that uses the STP16CPC26. We have two chips daisy-chained together. The SDO output from the first chip never goes high. The SDO pin is definitely not shorted to ground or any other net, and is definitely connected to th...

Resolved! STP16CPC26 won't do anything

My apologies if this is the wrong ST forum... it seemed like the closest one to the part I'm using.I have a new STM32F072 board design that has a STP16CPC26 LED driver connected to one of SPI busses. I just could not get the chip to do anything using...

Resolved! MOS FET with built-in TVS diode.

I want help to understand this. The STM MOS FET STP6NK60ZFP has a MAX gate-source voltage (Vgs) at 30V. In order to protect it from ESD it has a built-in TVS diode. Over 30V it can fail. But the bulit-in TVS has breakdown voltage (Vbr) set at 30V. It...

Resolved! PowerFlat 8x8 HV NC pins

Hi ST Community! I'm working in a HV power design (400VDC) with a STPSC6H065DLF Schottky diode. I can see from its datasheet that pins 1 and 2 are not connected internally, but I can't find any recommendation about what to do with those pins. Would i...

STM32G0B0 STANDBY, PLL consumption

Hi everyone,I'm stuck on the transition from my low-power mode versus my power consumption.I already have a “sleep.c” code that is capable of putting the device to sleep at 2uA power consumption (which is my goal, everything's fine here).This code ex...
