@TDK , @Peter BENSCH we are facing SPV1040 IC failure (burns) in the field, after around 3 months of installation, attached schematic and our solar Panel speciation Voc:4.55V, Vm:3.85V, ISC:1026mA, Im:950mA.Battery spec - 9000mAh, 4.2V Lithium ion.
Mystery IC number ?
Hello allI don't know if this is the right sub-forum, I chose the one that seemed the closest.I've been spending a bunch of time trying to find the part number of a seemingly simple IC, but just hitting walls. I've Googled using the manufacturers nam...
Explain RC filter of STGIB8CH60TS-E Smart Shutdown Circuit?
Hi everyone,I’m using the STGIB8CH60TS-E IPM in my motor drive design and trying to configure the smart shutdown (overcurrent protection) function using the CIN pin.As per the datasheet, the internal comparator reference voltage (Vref) is typically 5...
powerstep01 (stepper motor skipping steps after few hours of operation)
Which alarm to read if our motor skips steps while moving? The motor works fine for a period of time like for 4hours and then randomly starts to skip step while moving in forward direction whereas in backward direction it moves fine. We are using 1/4...
EVLVIPGAN65DF radiated EMI
EVLVIPGAN65DF application note states that the provided reference design is compliant with IEC55022 Class B conducted EMI. How about radiated EMI? Is there any measurement in this regard?

Hello Team, We are using VN9E30F High Side Driver, when we try to communicate it through SPI, the SPI Error Bit of Global Status Byte is getting Set and Reset as well. We are Following Below Configuration for SPI:- Could anyone help me to verif...
Strange High Side Switch behaviour / VN751PT
HI! We have from time to time defect High Side Driver. Most of the defects occur after the first few power on cycles. The High Side Driver and the RGND Resistor (120Ohm) gets really hot. The resistance between GND and the Status Pin is then much l...
Resolved! Demo Code of AEK POW BMSLV
Hi, I wanted to ask the group if the demo code "SPC58EC - AEK_POW_BMSLV application for discovery" already includes automatic cell balancing, or if it doesn't, or if it needs to be enabled somehow. I was also interested in knowing if there was a GUI ...
