virtual-fly/VF_MOTOR_DRIVER
VF_Motor_Driver is an open hardware power distribution board, designed to be part of a larger modular system. This design is based in part on the OpenFFBoard TMC4671 driver board, licensed under the GNU General Public…
Yes. The symbol is Driver_FET:LM5109BSD and the footprint Package_SON:WSON-8-1EP_4x4mm_P0.8mm_EP2.6x3mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
WSON-8-EP(4x4), with 9 pins. Its footprint is drawn on this page.
Texas Instruments publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C544701, with 408 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the LM5109BSDX by Texas Instruments, the LM5109ASD/NOPB by Texas Instruments and the LM5109ASDX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
