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...
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Hi all,I was wondering if there is any pin to pin replacement for VN920SP-E?VN920SP-E is obsolete now, and one of our main products needs this to function.Any help would be appreciated.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？
STSPIN958 H-Bridge, current measurement in II and IV quadrant?
We have a prototype board with the STSPIN958 full bridge but we see that it cannot measure positive current (in coil) when the voltage is switched negative, output shows current = 0.We switch from 48V to -48V on the coil. (turning the magnetic field ...
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...
ViperPlus Series for DCDC
I am trying to build a DCDC Converter with following conditionsVin: 400~600VDCVout: 12~15VDC(Isolation is not required)Current Rating: 100mA~300mA(Not really stricted)I can see DC application simple schematic at the first page of the datasheet for Vi...
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...
