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...
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...
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...
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...
can PG pin of ST1L08SPU33R be left floating if unused?Datasheet does not specify it.
Hi all,I was wondering if there is any pin to pin replacement for VN920SP-E?VN920SP-E is obsolete now, and one of our main products needs this to function.Any help would be appreciated.
Dears, I'm working on an audio project, and I'm searching for LED drivers with no PWM, to avoid noise. I need one sink (common anode LEDs) and one 'voltage' (common cathode LEDs) driver. Could you please suggest two drivers, which could comply with...
Could you tell me the minimum DC current gain(hFE) for the BUF420AW？
Hello,I have designed the same schematics of the website : The output should be 18V and no significative current (1-5mA output because MCU off). I have tested the input voltage at [80 ; 200] V and I have the same problem. The chip try to start during...
Dear ST team , We are currently finalizing our hardware design using the L9678P, with a focus only on deployment functionality and functional safety compliance according to IEC 61508. I’ve gone through the datasheet and functional descriptions i...
