I am trying to make a Vedder’s Switch that you can use a momentary push button to turn it on and off.
Im wondering if this is the right regulator that handles the current:
Specs:
Wide Input Voltage Range: Operation from 4.5V to 50V
Overvoltage Lockout Provides Protection Up to 60V
Internal High Side and Low Side Power Switches
20mA Output Current
I know that, but I wanna make that you use the power from the antispark switch to an atmega328 microprocessor that tolerate max 100mA. and 1.8 < 5.5V. But I dont know which regulator I shall use for that…
Mhmm, I meant not replacing the mosfet but adding a regulator that turns the voltage to 3.3/5 and 50mA output.
Not only that, connection via UART to VESC, and has a 2.4GHz radio too, maybe bluetooth too on my next version so you can turn of the power with your iPhone etc.
If your going the custom route, use TI’s webench tool to design a regulator for you, give it your input/output voltages and a current output and it’ll do most of the design for you.
That’s exactly the setup I’m using, but with the 5v from VESC, take care of a good filtering before feeding power into the arduino and radio module or you will have conection issues
The driver chip (DRV) has an integrated buck converter
