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...
What is STLQ015M18R maximum quiescent current at light load
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.

PCB routing guideline for L6566BH
Posted on December 22, 2016 at 07:48We have started working on PCB for L6566BH based design for 277V and 480V. Now we require some PCB layout Guideline for the chip, which is generally available in case of other Power Supply switcher, We were trying...
Measuring DC power using STPM32 evaluation board
Posted on December 20, 2016 at 21:35Hello,I am currently developing a device to measure AC or DC current on the same channel, depending on what type of voltage source the end user decides to connect to that channel.We are thinking of using the STPM ...
