Posted on January 12, 2017 at 08:51Hi AllI am currently testing a power supply system with a bulk power supply backplane (30V, 12A) and cards that slot in on the backplane. The cards come in various different flavors (24V, 12V, 5V) all using L7986A ...
Posted on December 29, 2016 at 15:48I ask about one 12v tvs-diode of ST-electronics manufacture - Bux c543. It was found on sp0812n samgung 80 gb hddand was soldered through due to overvoltage from psu. Now I need to relace it, but I cannot find any...
Posted on January 05, 2017 at 13:09Hello,have a little Problem with the Timer (TIM1) on my IHM001I want to brake the motor down to zero and then i want to align the motor to different positions like a stepper motor.The Braking down to zero works, th...
Posted on January 09, 2017 at 00:16I try use two drivers. I can switch on/off any output channel, but I can't use brightness registers correctly. Manual has description how work with one driver. But if I send brightness data to first driver, a secon...
Posted on January 09, 2017 at 04:53I notice wAux = pDVars_str->wPseudoFreqConv /pDVars_str->SensorPeriod[pDVars_str->bSpeedFIFOGetIdx].wPeriod; hAvrgElSpeed = (int16_t)(wAux); hAvrgElSpeed *= pDVars_str->SensorPeriod[pDVars_str->bSpeedFIFOGetIdx].b...
Posted on December 09, 2016 at 03:38Hi,We designed a battery charger using SPV1040. The output voltage is fine;however, during the charging process, there is a large fluctuation on the input voltage : 500mV ~ 1V. Ideally. This input voltage should ...
Posted on December 08, 2016 at 11:59I have a range of ideas that I want to try using a motor and movement as a generator. Can I omit the MPPT resistors from my circuit and still use the IC as a battery management and linear regulator?Secondly when I...
Posted on January 04, 2017 at 13:37Hi guys, I'm designing PSU for battery-powered board.Source is a single Li-Po cell, output voltage is 3,3V @500mA (peak, average would be less than 400mA).I used STBB1-APUR to get 3,3V from battery (2,7 to 4,2V) bu...
Posted on January 02, 2017 at 16:01Hi,I see strange behavior of L6482H output toward FET gate, I'm expecting that the high side output amplitude will be the Vboot (Vs+Vcp) to allow proper Vgs and low Rdson over the FET but some time the amplitude is...
Posted on December 28, 2016 at 08:57I am using STLQ015M18R to drive a light load of 0-2uA at temperature up to 70c,My question is what is the maximum current that STLQ015M18R consumes from VIN excluding the 2uA it drives the VOUT.
