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...

Question about HALL_CalcAvrgElSpeedDpp function

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...

Troubleshooting with spv1040 MPPT

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 ...

Energy Harvesting - SPV1050 setting MPPT

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...

STBB1-APUR power grounding

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...

L6482H Gate output sometime VS instead of Vboot

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...
