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...
Resolved! SPSB081 : ISO 11898-2 qualification report
Hi all, I am interested in the SPSB081, it is fully compliant to ISO 11898-2. Where can I download the ISO 11898-2
Triac phase control power controller design for an inductive load
I am trying to produce a triac power controller for a large mains solenoid which is for a lab demonstration of electromagnetic induction. I have not had much success!My initial attempt used a simple 2-wire design as shown in figure 1 of ST's AN308 a...
VN9E30F - sample software
Hi everyone, i am strugglig for a while trying to bring vn9e30f 24bit spi high side driver to life. Don't you know about any "sample" software which shows exact way how to change (for example on channel 0) duty cycle on given channel ? I tried almos...
Resolved! Using more than a single X-NUCLEO-IHM06A1 evaluation board
HelloI want to use 3 x STSPIN220 for controlling 3 x stepper motors (motorized lens: Zoom, Iris, Focus). Currently to test lens I want with X-NUCLEO-IHM06A1 evaluation boards (with NUCLEO-F401RE). In stm32_nucleo_expansion_boards_motor_control_select...
Control IC for boost converter with ZVT using auxiliary switch, for PFC (line current shaping) ?
Dear Sir/Madam,we are designing a PFC input stage for a power converter. High efficiency, low power loss, and low EMI (low dv/dt, low di/dt) are all important requirements. We have identified a suitable power topology for this stage: Zero-Voltage-T...
Resolved! negative shunt in M2P45M12W2-1LA
Hello,We want use sixpack SiC Power MOSFET module for drive a low power hi voltage motor.For safety reson I want measure the phase currents with 3 shunts connected beetween low side source and negative, instead one. With this package aren't avalable ...
