L6480 UVLO-Bit problem. Can't get it flip to 1.

Hello,I use the EVAL6480 Board and the STM32 F446RE as MCU to communicate to the driver.My Steppermotor [1] (not exactly this but very similar) has oer phase a resistance of 1,2 ohm.My Problem is that the motor does not turn because the UVLO flag is ...

UVLO flag always on

Hi, Using IHM03A1, I'm driving a 48V-9A motor.According to @Cristiana SCARAMEL (Employee)​ recommandations, I add 15mOhm/3W resistances in parallel of R1 and R2, so R1 and R2 value is now 13mOhm, I choosed current mode, set run current to 10.2A (132....

Kindly share updated MFD, COC, REACH certificates of L7912ACV.

Hello everyone, I resently bought an starting current limiter. For some adjustments I need to know which IC this is on the picture. After hours of searching I could not found any informations besides that ST produced it. I hope someone can help me.

Thank you :)

I'm working on an old board using a STPM10. Can someone give me an explanation (and a formula, if any) on how Ks (current sensor sensitivity), R1 ed R2 (voltage divider sensitivity) are related to P (Led power sensitivity). Thanks.

STPMIC1 I2C program

I have a STPMIC1E on my board, it is used with a STM32MP157 chip. I am currently trying to program the PMIC IC via the GUI but it won't connect to the bus. It says USB to I2C bus not connected. Any ideas?Thanks
