Hello everyone, is a low pass filter a viable way to deal with transient voltages? I'm working on a DC motor driver which uses a FT232R for USB to RS232 communications. Right now the FT232R stops working whenever I run my motor, from my scope I can see transient spikes that go as high as 7V. I'm wondering if I can use a low pass filter to correct this. I would use a TVS diode but its tough to find a through hole component with the correct clamping voltage. I've also tried a zener diode, it helps but it just isn't fast enough to catch everything.
Lastly, I've verified this isn't a software bug. If I send my packet without the motor attached everything operates as expected. I get a nice square wave out of my PIC output for a given duration and the micro sends a ready packet back after a given duration. Thanks in advance everyone.
