In STPM34 Can we connect two shunt Resistors for measuring Current? If yes How?

As a rookie college student, I wanted to know the calculation.This is a formula that appears in Application Note:AN1089 of L6561.

I am looking for documentation for the L9763 chip, SPI protocol. Do anyone have this? Or do anyone know where to download from?

SPV1040 produces little to no output

Same issue as @PK.3 (but I would like the response to be shared with the community :beaming_face_with_smiling_eyes: ) : using a 4 volt OC 425 mA SC series photovoltaic, and SPV1040 with circuit matching STEVAL-ISV006V2 except Rs = 0 ohms and no VR4 (...

Hello, I have a question about the STWBC. After the charge is completed the EPT CHARGE COMPLETE will show up in the protocol screen in the GUI. Once the device is charged the charger will not come back into ping status.

After a the device is charged the stwbc needs a power cycle before the it will come back in ping status. Is it possible to set the charger always into ping status after a charge is completed with the parameters?Thanks in advance, Marco

Possible for stusb1602 SNK to negotiate higher PD voltages without SPI?

I'm building a sink only type PD device using a SAMD21G18A and the stusb1602, because the stusb4500 was not available so we changed our design. I have i2c communication with the device, and can read/write to the NVM (although I'm not sure I have the ...

Snubber for a TRIAC controlled by phototriac

Hello, I'm designing an AC switch with a TRIAC. This TRIAC is controlled by a phototriac. The following connexnio is used : R1 and C1 is a snubber to protect the phototriac.   Is this case, is it necessary to add a second snubber (see below) to prote...
