How to validate the repetitive peak pulse current rating for a given MOSFET?
I was planning to use STP15N95K5, for one of the power converter application. I have RMS current for the switch around 4 A with repetitive peak currents around 30A (0.2 duty cycle with a frequency of operation of 140kHz). The switch operates at a DC ...
I think this 32 pin chip labeled 23257-B is related or a variant of ST72324 8-bit microprocessor. Can anyone confirm
does anyone know if this chip 23257-B is a variant of ST72324 8-Bit microcontroller? I am looking for a datasheet to confirm, thanks!
Is 23257-B related to ST72324?
I am trying to identify this 32 pin chip (23257-B) used in an automotive application (see picture). I am unable to locate any spec sheets. I am pretty sure it is a variant of the STMicroelectronics ST72324 8-bit microcontroller. Can anyone confirm a...
Resolved! SPW04SA - How to use additional headers in Http POST & GET requests
I'm using the SPW04SA module and want to write sensor data to the Azure Storage Table service. To achieve this I have to add special headers to my requests.Until now I couldn't find out if/how this can be done using AT+S.HTTPPOST and AT+S.HTTPGET. As...
How to send AT commands to the integrated wifi-module using internal uart in B-L475E-IOT1A
I want to communicate with the wifi module integrated in the STM32 iot node using AT commands, so i configure the internal uart3 used by the module to receive AT commands and transmit the answer to the AT command but it doesn't work ?
L9678P typical circuit
Does anybody have this L9678P typical circuit and could you explain the component select method and IC pin function?
BTA26-800 SPICE MODEL
I used spice model downloaded from ST product page. But model behaviour is highly strange in LTspice XVII. There is 60V Gate voltage in I. and IV. quandrant. Negative gate current turn triac ON only in one quadrant.Is it possible to use ST models in ...
Does anyone know what this 32 pin chip is? Marked "23257-B" I think it might be equvalent to an ST72324 8bit MCU
I am trying to see if a chip marked "23257-B 1MU2114" is a predecessor to the ST72324 8 Bit MCU. It is used in an automotive application, and the documentation says the chip on the board should be an ST72324, but the "23257-B" is there instead (see p...
NMI trap
Hi ST10F276 group,we have used St10F276 many years. It works very well. But one project generated random NMI trap recently, and crashed the application. My question is how I can back to user application from NMI trap (interrupt)? So far I only can...
