Robust DC brushed Motor Driver
« on: June 17, 2020, 11:46:09 am »
Hi,
I want to design a 5-10A , 36-52V DC brushed motor driver, and I know that there are tons of stuff out there, But I want to know who has done it better,and get some Ideas, Do we have some cool open source project for that, like the ODrive for Brush-less versions ;)

make you life easy and use two high current smart half bridges, ie something like

https://www.infineon.com/cms/en/product/power/motor-control-ics/brushed-dc-motor-driver-ics/single-half-bridge-ics/btn8982ta/


won't get you up to your 52v, but will save a lot of hassle and be very robust (ime, you can dead short those ICs with a screwdriver across their output pins at fully current and they survive....)

If you want to go to a descrete's solution then it's a LOT more work with mosfets and drivers etc and you'll have to provide all the necessary safety (overcurrent, shortcircuit, de-sat detection etc) yourself

Thanks for the feedback, I'm interested in reading the motor Current too, this device does not provide this feature, also it seems that it has a supply voltage of up to 40V only
