L6470 abs_pos bit length not as large as literature claims? & busy pin ending early.
Posted on May 31, 2016 at 03:18From the literature, the abs_pos value is a 22 bit 2's complement integer. but when i move the position above 32768 (16 bit 2s complement maximum), the value resets to negative. I.e. the abs_pos value acts as a 16 bit ...

LD3985 question
Posted on January 19, 2017 at 21:03Hello to all!I have one more question about LD3985. I didn't find any information about limitations in high current modes. Output current of LD3985 is 150 mA. Can I use it for 250 mA load (for example) in continuou...
Preventing/Limiting inrush current on L7986
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 ...
How find datasheet, characteristics and replacement for Bux tvs diode?
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...
PWM Timer after Motor Stop
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...
Resolved! LED1642GW series connection, brightness.
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...
