Information and waveforms plot missing in L9945 Datasheet

Hi,Can we have some more data for L9945? Datasheet provides very less information. Some timing waveforms for all 8 channels(or may be only one channel, which can be replicated for the other 7 channels). Functional block diagramTypical application sch...

Chip markings on the STSPIN32F0A

I recently purchased these from element14: https://in.element14.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=91&urlRequestType=Base&partNumber=2797963&storeId=10186.The ones I got show this as the chip marking: https://i.imgur....

Resistor guidelines for LDL212 adjustable

Have specified LDL212 adjustable regulator in new device. Very limited information in the datasheet for selecting the R1 and R2 values. Assistance appreciated. Target VOUT is 3.6VThanks in advance

Currently I am using "STEVAL-SPIN3202" with "STSW-SPIN3202" to drive a 12V/30W, 16-pole BLDC motor by sensorless control.

However, when I pressed the button USER1 on "STEVAL-SPIN3202", the rotor spun for couple turns and then stalled. I did it several times, but got the same results. I have checked p.50 of UM2310, but haven't got the motor running. What are possibilitoe...

How long will STTH810D diode last at Tj = 126degC?

We are using the STTH810D in our new 60W offline  Flyback LED driver. It is dissipating 4W. We measured its metal tab as operating at 115degC. Therefore its junction is operating at 126degC.This product is supposed to operate for 8 hours per night , ...

L6480 best driving (from motor motion perspective) strategy question

Hi all,I'm developing a bipolar stepper motor application by means of a STEVAL-PCC009V2 + EVAL6480H boards coupled together.My application have to follow a position by means of an incremental encoder that is connected to the encoder quadrature module...

EVAL6480H-DISC

Posted on December 18, 2014 at 17:57Hi,does anyone know when the EVAL6480H-DISC will be available in the UK? Also will it be cheaper than the EVAL6480H evaluation board?Thanks in advance,Howard Smith #eval6480h #eval6480h-disc #l6480

L6591 issue

Hi at everyone,I designed a open loop dc/ac converter, but I met a big problem. The high side output did'nt work correctly over the 40V of Vhv. Over that value the output goes out derivates and the resistance from pin 14 and pin 13 is 5ohm. Aflter a ...

Choosing a reliable DC / DC converter to power the controller (12V / 5V)

Hi!I design a board on which there will be several microcontrollers (STM32 and ATMEGA328), 12V comes on the board and I need to lower this voltage to 5V. In addition to the controllers, I will power a few more sensors and LEDs.I am trying to find a r...
