Power management

I use DC-DC ST1S14. Vin = 12V. Vout = 5V. The entrance of EN2 is used for permission of output tension. At a temperature of -40 the chip is not always started when giving EN2 = 6V.

STC3115 wrong SOC values

I am using STC3115 on a custom hardware. We have followed the reference design as suggested by ST and also used the driver suggested by ST. I am facing the following issues with this setup1) Sometimes (very rarely) the  STC3115 is not able to detect...

Hello guys, my name is Nicolas, iam from Argentina. Who has the MAR9746 voltage regulator datasheet? this regulator is inside of ECU. Thank you very much !!

L7987L switch mode power supply battery charging application. My question will significant current from the battery flow into the L7987L when there is no input voltage but the input is open circuit?

L7987L switch mode power supply battery charging application. My plan is to have a rectifier followed by the L7987L buck-converter then a rechargeable battery. There is some protection provided by the Colomb counting current sense resistor.My questio...

VNQ5050K input4 is not normal，please help me to slove it�?Thanks

Has anyone out there got an IOC file for the Nucleo-X-PLM01A1 PLM project? I have just started with STM32 and don't feel confident enough to integrate the "example" files (that have no IOC files) with manual initialization.

Oscillation on back EMF measurement using the STSPIN820 and a stepper motor

Dear community,Scope of the work: I'm trying to measure the back EMF of a stepper motor. I'm following the ST application note AN3327, which suggests that the back EMF is measured as the residual voltage on the coil when i_coil = 0. Problem: when mea...
