Change the internal resistance of "2STBN15D100"

The internal resistance of "2STBN15D100" is described in the datasheet as shown below.By the way, if you actually measure the resistance between Base(1) and Emitter(3), it will measure around 12K ohm.I think that the data sheet will measure around 8K...

Need powerstep01 sample circuit for reference.

sample circuit need

For a new application,we need an AEC Qualified part with the specifications same as VIPER16LN.Is there any AEC Qualified Buck convertor with the same spec as VIPER16LN is applicable with ST?

Hi, for the STM32F446 series timers in encoder mode, which interrupt flag is set when an encoder phase state error is detected? In a presentation of the STM32G4-GPTIM it is mentioned that this feature exists, but in the f446 refman I cannot find it. Thx!

Is STUSB4700QTR power delivery IC compatible to be integrated with LLC Topology ?

I have to implement a power delivery system, for which I came across the power delivery IC ( STUSB4700QTR ) . But looking at the reference designs given in the Datasheets it can be seen that it has been implemented with the Buck and Flyback topology....

Is it possibile to power the board B-G431B-ESC1 with a 2s battery pack? I look the schematic and there is not an electronic limitation (all the components and uP are powered with +5 or +3.3) , so I wnat to know, why there is this limitation.

It appeared that nobody answer on spv1050 questions.. I had same problem as ask before : could not activate ldo if there are no charge ! even if battery is full! This is crazy! Also boost buck not working as expected.

Well, I have a lipoly single cell and ixolar solar cell from iXys (Vmpp = 4.3v) connect to the spv1050.Buck boost not working correctly, efficiently is worst bad. (I got onlt a fraction of Amp from a direct connection to my battery!)it is impossible ...

CS pin information

I suceed to have information on CS pin like short to VCC, Loss of GND. I havn't information like open load detection, or short to ground.I For open load detecion : I use external pull-up resistor Rpull_up as describe in datasheet and the motor driver...

What is the role of the CS and the SEL0 pins ?

What is the role of the CS and the SEL0 pins ?Is it possible to determine if the motor connected to the VNH7070 is in short to ground or if there is no Motor connected ?Thank's

Is it possible to use Viper12A with a bridge rectifier input instead of half wave rectification?

I am using Viper12A as aux supply for sensors in a bigger Power supply system for sensors. I need to know if the line rectification circuit is possible using Bridge rectifier network. The output power needed is less than 1W with 16V output. Thanks in...
