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...
Resolved! can PG pin of ST1L08SPU33R be left floating if unused?
can PG pin of ST1L08SPU33R be left floating if unused?Datasheet does not specify it.
Resolved! VN920SP-E replacement
Hi all,I was wondering if there is any pin to pin replacement for VN920SP-E?VN920SP-E is obsolete now, and one of our main products needs this to function.Any help would be appreciated.
LED Drivers - audio product - no noise (no PWM)
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...
Resolved! The minimum DC current gain (hFE) for the BUF420AW
Could you tell me the minimum DC current gain(hFE) for the BUF420AW？
Resolved! VIPER06 no-isolated can't start (over current protection ?)
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...
L9678P Deployment-Only Use Case – MCU Pin Mapping Confirmation
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...
Resolved! how to setup the EV-VN1048F?
Hi ST communityi just searched the setup of VN1048F then found out there are two evaluation board(EV-VN1048F and EVSPC582B).In this user manual of EV-VN1048F, it said this EV-SPC582B is supposed to be programed as described EV-SPC582B user manual. so...
