Title: L298 Mosfet alternative
Post by: ricko_uk on June 12, 2020, 07:36:54 pm

Hi,
There are plenty MOSFET H-Bridge motor drivers but cannot find an equivalent/replacement for the classic L298 ( https://www.sparkfun.com/datasheets/Robotics/L298_H_Bridge.pdf (https://www.sparkfun.com/datasheets/Robotics/L298_H_Bridge.pdf) ).

I need it to:
1) be able to control every every half bridge independently so for a full bridge I can have all 4 combinations (high or low for each side)
2) ideally up to 60V but can compromise to 35V
3) 1.5A minimum but preferably 2A

Any suggestions?

Thank you :)

Took me 5 seconds to turn up the L6203, anything wrong with that if you found it already ?

Say DRV8876 https://www.ti.com/store/ti/en/p/product/?p=DRV8876RGTR&HQS=OCB-tistore-null-storeinv-invf-store-octopart-wwe (https://www.ti.com/store/ti/en/p/product/?p=DRV8876RGTR&HQS=OCB-tistore-null-storeinv-invf-store-octopart-wwe) or DRV8874 for lower heat dissipation.

Or LMD18200 3A 55V H-Bridge, or LMD18245 with integrate dac.

Thank you all :)

Forgot to specify it needs to be SMD. But the DRV8876 works very well. Thank you all! :)
