I suspected that I bought a fake Viper22A, can I tell it from the silk screen? One is obviously silk screen, and the other is suspected of laser carving.

SPV1040 behaviour with a battery charger IC
Hello,I am wondering about the behaviour of the SPV1040 MPPT converter used with a battery charger (specifically the LTC4162-L but I think it would be similar with any battery charger IC). I need to charge a 2S Li-ion battery which is why I connected...
High frequency (high pitch beep) sound when start motor
Hi,I'm using STM32F303RB with ihm08m1 to drive a 36V BLDC motor. When I start motor, a high frequency sound (like a high pitch beep) is being made in the motor. The sound is a problem and very annoying, is there any way or solution to avoid this soun...
STC3117 system integration
Application note AN4870 (architecture overview) refers to "Charger IC" connected to microcontroller via I2C and to STC3117 via CD.Can you indicate a suitable Charger IC ? My project is a "true" capacity tester for single Li-Ion cell (18650). Do you ...
in the datasheet of LED2001, Figure 20, 21, why the thermal pad and PIN8 not connected on the top layer?
Dear Expert, from the bottom side, seems to me that Pin4, thermal pad, and Pin 8 all connected to Gnd. but from the top layer, there is a gap between the thermal pad and pin 8. if my observation is true, why not just connect the thermal pad copper a...
Resolved! What are STSPIN233 OC trip time (tOCSD) and OT trip time (tTHSD)?
Hello,the overcurrent and over-temperature trip (deglitch) times are not given in the datasheet.My focus is mainly on the OC trip time, that's because I intend on adding series inductors to the motor phases to protect from motor windings short, thus ...
Resolved! How to install "en.x-cube-spn3" to use it in STM32CubeIDE
Hello everyone, i'm working with a nucleo F401RE and the X-NUCLEO-IHM03A1 High Power Stepper Motor Driver (Powerstep01). I've been having problems for several days now and I've been looking for solutions but without success. I downloaded the .zip fil...

ACST1635 AC Switch reference design help
Hello experts,I've been trying to build a small home automation project using ESP32, PubSub client and an MQTT broker on Android. Rest all is fine, but I was trying NOT to use a relay for controlling the appliances. While considering Solid State Rela...
Can I use the VNPxxN07 series as a replacement for the LM395s in this (attached) circuit?
Hello! I am interested in building the design in the file below but rather than using the LM395 transistors, since they are difficult to acquire, I was wondering if I could substitute some VNP5N07s or similar transistors for the LM395s as a more mod...
