Wireless transmitter controller IC

Hello,we are building a wireless charger for smart phone charging 5/10W, suggest the suitable Qi transmitter controller.

STBC03: Can the BATMS_EN pin miss getting asserted, or get locked in 'Off' mode?

We're seeing an odd behavior in the STBC03. We keep BATMS_EN asserted at all times, as we are not worried about wasting that little bit of power. Once in a while (1%?), on power up, BATMS_EN is high, the LDO is outputting 3V, the battery is ~4V, but ...

L6566B reset indicating shorted

We designed an AC / DC power supply with the L6566B with the help of the eDesign tool. We manufacture a 5-piece pilot lot and are encountering a problem with two parts that do not start the L6566B.Taking some measurements we realize that at pin 5 (VC...

3-Phase Motor

Hello,I ordered STM32F769I-EVAL and IHM028V2.BLDC motors, mc_startmotor, mc_stopmotor and so on I was using commands using atollic. Can I also do these commands on a 3-phase ACIM on the atolic?

Hi - we have the STEVAL-STRKT01 card up and running - all looks well - but the power consumption level is still showing a 1.6mA quiescent current when Sens/USB and MEM blocks are disabled. the Accel has also been disabled by isolating on the board.

Can you outline what is the lowest possible current consumption is for this card and how this can be achieved?An urgent response would be much appreciated.

Hi, is it possible to use X-NUCLEO-IHM03A1 with a Nucleo-144 board? Are they compatible? Regards, Giuseppe Reale

We are using L7805CV , Input voltage = 33V output expected = 5V with 20mA of current requirement But we are getting 7.5V, the L7805 may know the reason? according to datasheet input voltage is 35V

Current supplied to teh micro controller board alone,it is nowahere connected,Still 7805CV not able to deliver the 5VPlease find the attached circuit and let us know please let me know why this circuit is not working or let us know the input voltage ...

How to identify BLDC motor is rotating or in steady state using STEVAL-SPIN3202 board

We need to identify BLDC motor state(rotating or steady) when board power up. The issue i am facing is, BLDC motor stops with ****, due to initial init functions.Is there any way to identify that bldc motor in rotating state or steady state, from sof...

What is the maximum junction temperature of the LD56050?

The datasheet states an "Operating junction temperature range" of -40 to +85 degC in table 3. The thermal shutdown in table 6 is given as 160 degC. How do these two relate?
