Power management

I would like to know when I will be able to get hold of L6480 ICs from distribution

We have had 3 dates in the last month with different distributors where items have been shown as coming in and we have ordered; but when the date passes they become marked as 45 week lead.

SRC0GS22D POWER RESET

I am trying to reset the power by controlling GPIO3.3V.However, the initial power is ON and OFF only, and there is no control thereafter. 

PM8800 PoE Issues (high ripples)

We designed board with PoE capability using ST PM8800 chip. We encountered some problems.Issue #1When our board is powered from external power supply (Vin(AUXII)=32V) we get output voltage with high ripples and PM8800 nPGD is inactive (High). Ripple ...

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.
