Power management

is the STSPIN32F0A suitable as a gimbal motor controller without hall sensors(or other sensors)

Im currently looking for a more intelligent replacement driver for our robotics wheels. Currently we use very small BLDC "WITHOUT sensors and it will stay that way" We have typically controlled the BLDC through a "PWM Table array" using 3 PWM chann...

Oscillation in STW88N65M5 transistors

We are testing a 300kW inverter prototype, consisting of 12 modules of 25kW, connected in 3 phases of 4 modules in parallel.Each 25KW module has a full-bridge exit stage of 8 STE88N60M5 transistors, in parallel to 2. The sineworm modulation of the PW...

How to use st flash bootloader for stnrg ic ?

Hi all,I want to configure option byte of stnrgpf01 ic. How do i configure it with st flash loader ?Best Regards.Ferudun..

I am using your BTA24-600BW triac to control a 1.25HP AC motor. Unfortunately, I am unable to maintain enough torque when a load is applied to the motor. Are my design issues due to triac or because motor is on A1 of triac and not A2?

Problem in stm32f103c8t6 while running motor on load condition

Hi friends, I am driving bldc motor using stm32f103c8t6. And i measure the rpm of the motor using the hall sensor pins. While running motor on no load condition....Motor runs good .Rpm is also measured and i monitored in keil debugging session, which...

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.
