Dear All, I've a problem with my step-down regulator L7985A. On power up, the DC / DC is activated when the ENABLE pin reaches about 880mV, while on the datashhet it is reported 1.2V as the ON threshold.

92E540
I want to search datasheet about '92E540'. But I couldn't found that. Can I get the datasheet about IC '92E540'?
STSPIN32F0 12v internal regulator problem
Hi,I designed BLDC motor driver 12v powered card with the STSPIN32F0 chip and developed my own software. My codes run smoothly on the STEVAL-SPIN3201 kit.But on the own my card, 12v regulator outpus voltage inside chip didn't rised more than 1v.When ...
I've been trying to write my own code for a BLDC sensorless control. I've been having difficulty detecting bemf in the open winding.
My spice model looks good but in the hardware the bemf does not cross Vd/2. On some phases it is above Vd/2 and rising while on others its below Vd/2 and falling. I'm using a STSPIN230 as the triple half-bridge and am pulsing both the high-side and l...
What is the body marking for a LD3985M33R voltage regulator?
Asking because there doesn't appear to be any mention of body markings in the datasheet.
STEVAL-ISB043V1 documentation and software
Hello, we just bought two evaluation kits ST : STEVAL-ISB045V1 and STEVAL-ISB043V1.It seems impossible to find documents relatives to STEVAL-ISB043V1 such as document we found for STEVAL-ISB045V1 :UM2367 "Getting started with the STEVAL-ISB045V1 2.5 ...
Two LD29300 in parallel for increased output current
Hello,I'm trying to convert 20V/5A SMPS power to 19V for my noise-sensitive application. I couldn't find a good buck converter for my design.I came across LD29300 and saw that the specs except the output current meet my requirements. So I would like ...
Resolved! Can anyone please send a minimum set of config parameters and digital input settings for L9945 to - switch a high-side FET on channel 1 on and off via SPI - turn a motor in one direction on bridge 1.
No matter what we try, nothing happens. For case 2, the L9945 receives the PWM.Thank you in advance. Best regads: Balázs Bámer
