LP5521TMEV: LP5521TMEV altium files

Part Number: LP5521TMEV
Other Parts Discussed in Thread: LP5521

Hi,

i was wondering if you guys could share the altium sch, layout files for the eval board. is there a schematic simbol and footprint LP5521 that can be imported?

Thanks,

  • Hi Ramtin,

    Sorry that LP5521 is an old device and we cannot find original EVM design document now. Detail package information could be find in datasheet page46.

  • Thanks, 

    I have another question regarding this part.

    The datasheet states that when program memory has been loaded, the lp5521 can operate autonomously without processor control. However when the Eval GUI is used, the RUN tab would need to inserted prior to program execution. how does this work? how does the micro controller halt the motor driver IC? my design does not have a processor. i intend to program the IC and insert the EN signal to start the program. 

  • Hi Ramtin,

    I supposed that it cannot be achieved without a processor. We need to config registers and upload engine code to IC by I2C communication.
