DPDT switch using MOSFETs

Hi all,

I am trying to figure out how to make a DPDT switch using MOSFETs, transistors or whatever you think best.

I want to use a Hall effect switch to trigger the DPDT.

So if the first leg of the DPDT is X to A or B and the second leg is Y to C or D:

I want current to flow from A to X and Y to C. When the Hall switch is activated the current changes to B to X and D to Y. When the Hall switch turns off, it goes back to A to X and Y to C.

Here is the Hall switch I have:

Melexis MLX90217

Here's the datasheet:

Supply Voltage VDD Operating 3.5 - 24 V
Supply Current IDD VDD = 12V 1.5 3.0 4.5 mA
Supply Current IDD VDD = 3.5V to 24V 1 - 6 mA

Any help or reference on how to do this would be greatly appreciated.

Thanks in advance.

Best to you.

I would start with an H Bridge but since you don't mention the application nobody can really give good help. Th currents you show are low, a H bridge could be fabricated using transistors likely.

What voltage and current do you want to switch?

Yes, I forgot to mention what the switching load would be, thanks.

The switch current would be no more than 1 amp at 60 volts, less than 60 watts.

Speed would be no more than 500 cycles per second.

I'm building a motor controller. I'm pulsing a coil to drive a magnet rotor.

Thanks for your quick response.

Yep. Look up "H-Bridge". Not enable and direction are the simple ones. Control of direction, brake and coast for others. Discrete and IC versioons are available.
