EMF Chips or diodes? * SOLVED

Zap-o

Is there an IC that offers EMF / ESD protection, so that I don't have to use 4 diodes to make a EMF protected circuit like used on the output of an H bridge / in DC motors? My board is running out of room and I am looking for something small.


Thanks.

**** Solved this problem digikey sells them as an array ****

Zap-o,

A bridge rectifier will do the trick.

Connect the AC terminals to your motor, connect the + to your supply, and the - to your GND.
