How can i change rotation of motor?
QuoteHow can i change rotation of motor?H-bridge if you want to change the rotation direction. PWM if you just want to change the rotation speed in one direction.
If you want Higher +U, then you need transistors in front of the P-Channels so the gates can go fully high (up to U+) to turn the P-channels off.
So basically like this.When a control line is high, the N-channel MOSFET gate is High and turned on, and the NPN Base is turned on to bring the P-channel gate Low to turn it on.When a control line is low, N-channel MOSFET gate is Low and turned off, and the NPN Base is not turned on, allowing the resistor to pull the the P-channel gate High to turn it off.
