Resolved! External diode in L6390 for high switching frequency
Hello. I have a custom made board with an L6390 used to drive two MOSFETs. My switching frequency is 100kHz. I noticed that at low duty cycles the bootstrap capacitor was not charging correctly. Per the datasheet, I discovered that due to the interna...
STEVAL-SPIN3201. Incorrect signal waveforms to drive N-channel power MOSFETs
I designed PCB with STSPIN32F0 and my MOSFETs sometimes breaks down. I think because of break-in. I started to look at oscillograms and i was surprised. Then I took the STEVAL-SPIN3201 and repeated research. It's the same. I explored waveforms for ga...
RHFL4913A requirements on capacitance value between Vo and Adj pins?
The RHFL4913A data-sheet (Figures 4 and 5) show a 47nF capacitor between Vo and Adj pins. How critical is the value of the capacitance used here and what is the affect of changing the value?For example, if I only have a 15nF or 100nF ceramic capacit...
Resolved! STSPIN250 overcurrent
I have two questions about the STSPIN250:What is the overcurrent threshold? It's not listed anywhere in the datasheetAfter what interval is the overcurrent threshold triggered? The datasheet mentiones a Toff time, but that's for the PWM current contr...
Resolved! STSPIN32F0 vs STSPIN32F0A vs STSPIN32F0B
Hello ; We need to drive a sensored (HALL) BLDC motor ; we need to decide STSPIN32F0 series but we confused which one is the best choice for use ; we need speed control using the hall sensores . Also when to use volt control mode and when current ...
pins of RHFL7913A (Flat-16 package) Spice model seems wrong
I am working on RHFL7913A (Flat-16 package) and wants to simulate the components under different conditions. However, when I download and import it in the Orcad PSpice (Cadence), I noticed multiple problems:The reference number is RHFL7913 and not RH...
Resolved! Maximum current rating of STEVAL SPIN 3201
Hi, I'm trying to use SPIN3201 to run a bldc motor and the maximum current rating of the motor that i want to use exceeds SPIN 3201 rating, although SPIN 3201 is rated for 15A i don't see whats capping the maximum rating as the MOSFETS are rated for ...
STC3100 at startup
Hi,I just started to use the STC3100. I can read all registers but I don’t understand how I can calculate the State of Charge at startup. I followed the application note AN3064 and apparently I need a voltage measurement to estimate the State of Char...
How can I enable spv1050 ldo's
I have an eval board steval-isv019v1. It is for boost config of spv1050. I connected pv yo pv input connector, a li-po battery to battery output and a 22kohm load to ldo output. I measure pv input voltage as 1.5 volts, store voltage as 3.92 volts an...
