| FFF Compatibility | The pin assignment and thermal pad connection of L6472PDTR are an exact 1:1 match to L6470PDTR in the PowerSO-36 package.Both components use the identical PowerSO-36 package, allowing immediate physical interchangeability.While key electrical parameters match, L6472 uses current-mode control with up to 1/16 microstepping, whereas L6470 uses voltage-mode control with up to 1/128 microstepping. | Housed in a 28-pin HTSSOP package, which is completely incompatible with the 36-pin PowerSO footprint.The HTSSOP-28 package has significantly smaller dimensions and a different lead pitch, requiring a PCB redesign.It uses the exact same silicon die as the L6470PDTR, offering identical electrical and functional performance. | ||
 AI Summary | L6470PDTR by STMicroelectronics: Bipolar Motor Driver DMOS SPI PowerSO-36 Slug Up. | The L6472PDTR is a direct physical and pin-compatible drop-in alternative from the same STSPIN family. It features the same 45V and 3A power ratings but implements a current-control architecture with 1/16 microstepping instead of the L6470's 1/128 voltage-mode engine. This requires minor firmware adjustments depending on your registry settings but zero hardware layout alterations.
| The L6470HTR is the same silicon die housed in a smaller 28-pin HTSSOP package. It offers 100% functional, software, and electrical compatibility, making it an excellent alternative if you are able to perform a minor PCB layout redesign. This variant is ideal for space-constrained designs where the bulkier PowerSO-36 package is not strictly necessary.
