L298 distorts signal

I connected STM32 F334R8 microcontroller to L298 H-bridge. I made some measurements. The problem is output signal on L298 has quite slow slopes and is not as sharp as input signal. I do not understand ...

Why are the power pins on an L298 H-Bridge named "Vss" & "Vs"

I understand that Vs is where the H-Bridge gets it's power for driving the motors and that Vss is used for driving the logic, and they both sink to a common ground named "GND". My question is why are ...

L298N motor driver not working after connecting SPST switch

So when I had all wired as depicted in the first image, it worked fine, no problems. The red LED on the L298N board was illuminated and the dc motor was following commands from my Raspberry Pi. Now I ...

L298N shield gives relatively low ouput voltage and current

I am using a L298N shield together with an Arduino to drive a 42mm 2 phases bipolar stepper motor. The driving voltage for the motor is 12V and the logic voltage for Arduino and the L298N shield is 5V....

Output voltage from L298N

Is it normal to have a higher output voltage than expected from an L298N driver? I have read that there are voltage drops and it is usual to have lower output voltages, not higher ones. If it is a PWM ...

Datasheets do not mention and explain enough about current

I'm trying to build my first IoT project. I'm using an L298 motor drive, an MCU-6050 6 axis gyroscope and accelerometer and an Arduino Due. When going through their datasheets, most of the tables and ...

speed control PWM, DC motor, L298n with LPCxpresso 1549

this is my first post and I'm just asking a little bit about motor control in a team project, where I'm member of. This is a bit of a "not so serious" project so probably the solar panel system ...

Review of PCB design L298n

I'm decided to finally make my motor driver boards but I'd be happy to have some feedback as it's my first PCB design. It's mostly based on the datasheet of the l298n chip. So there is nothing much ...

Will this N-Channel Mosfet work as high-current motor controller?

We are building a mobile robot which will use two motors in a differential drive configuration to maneuver and move around, and we want to choose the right driver IC or transistor circuit for the job ...
