STGAP2D isolated half-bridge gate driver: very specific question related to on-chip internal voltages applied to the gate of GOFF NMOS transistors with respect to GNDISO_A/B and their current drain versus gate voltage (internal) characteristic

The reason I need this information is because I would like to use the two internal 'half-bridge' of the STGAP2D gate driver for directly driving a resistive load at ~ 300 mA (more explanation below). In addition, the configuration / topology I am tar...

It is a question of regulator RHFL 4913.

​It is a question of regulator RHFL 4913.There is a noise graph on the data sheet(DocID10005 Rev17 Figure 37), but there is a peak at 30 kHz.Is RHFL 4913 a switching power supply?If it is not a switching power supply what is the noise of 30 kHz?Thank...

STSPIN250's can I use 3.3V for it's logic pins?

STSPIN250's EN\FAULT and STBY\RESET pins are described as "Logic input 5 V compliant". Does it mean it only supports 5V logic or 3.3V logic will do the job of bringing these pins high?Want to use this device with STM32L496 MCU which is a 3.3 device.

STEVAL-PCC009V2 missing source file for IBUU source code, where to find it? Many trouble with this board and no answer...

Dear all,as stated inside the UM0935, page 8/53, §2.2 it should be on the package also:"The IBU UI tool includes the following items:�? Hardware content:– One board– BOM list– Schematic�? Software content:– DFU firmware– DLL files of the I2C, SPI and...

Can I use STSPIN32F0A for control PMSM motor?

I need to drive PMSM motor and I would like to use STSPIN32F0A . Can I use this IC for control PMSM motors ?

The interface firmware FAILED to reset/halt the target MCU FAIL.TXT message on my STEVAL-SPIN3201. How do I fix this?

My STEVAL-SPIN3201 was working fine yesterday and I uploaded a new program and the program didn't work. So I left and came back today with this error. I have reloaded the ST-Link firmware, but still the same message everytime. How do I fix this?

STEVAL-PCC009V2 firmware reflash

Posted on January 08, 2013 at 01:12I have STEVAL-PC009V2 communication board for the L6470 evaluation purposes. I saw some posts found bugs on either communication board or PC software during the evaluation therefore I went to the website and downlo...

VNQ5E160AK-E (new design) vs. VNQ5160 (old design): can current sense pins stay unconnected (and CS_DIS set to GND via 10k resistor), so the old PCB design can be kept?

We are using VNQ5160 in a project, but those chips are now not avalible and we would replace them with VNQ5E160AK-E. Footprint and switching power is the same, the only main difference is in status pins, where older chip has status outputs and new ha...

i am trying to implement a CAN Interface using STM32 Nucleo Board L4R5ZIusing cube mx but not succeeding and not finding any example of same. If there is any example of CAN Interface pls provide
