Heat sink used on DRV8432EVM

Mark Grochowski

Is the aluminum extruded heat sink that is used on the DRV8432EVM motor drive evaluation board, p/n "HeatSink_DRV-EVM_35Wx80Lx38T-40P" available for purchase from TI or another heat sink vendor?

Hi Mark,

TI does not sell this heat sink on its own. You can purchase similar heatsinks through Digikey.

I have the same question -- I've never used a top-mount SMT heatsink. Phil, can you recommend one that will probably work, or explain how to select a mechanically compatible one on Digikey?

Hi Luke,

Please see post e2e.ti.com/.../608996

This information is for the DRV8332, which uses the same package as the DRV8432.
