Do I need I need a diode

[ernest]

Hi all your wisdom please.
Picaxe18 High Power project Board CH1035A.
Re: The 4 FET Drivers.
I have a 12Volt DC Motor connected to a FET Driver . The Motor is fitted with a 220nf
Suppression capacitor.
Question: Do I also need to fit a Back EMF suppression diode IN4001?
Thanks Brian.

Hi Brian

No you do not require a diode as they are part of the CH1035.
Refer to the schematic on the data sheet

See the CHI035 Datasheet: http://www.picaxe.com/docs/chi035a.pdf

Schematic on the last page - shows the freewheeling diodes between supply and outputs.
Labeled as "D1" for the first Channel.
