TPS659037: TPS6590379ZWSR difference between dowloaded symbol ans schematics

Johan Bendz

Part Number: TPS659037

Hi,

I have downloaded the TPS659037 symbol from TIs homepage and comparing it with the ARM MPU AM572X Industrial EVM I have found tthe following differences:

K4 marked as NC in the downloaded symbol is used as LDO5_OUT in the EVB

K5 marked as NC in the downloaded symbol is used as LDO8_OUT in the EVB

L4 marked as NC in the downloaded symbol is used as LDO6_OUT in the EVB

Are those pins NCV or used in TPS6590379ZWSR?

Johan,

The TPS6590379 is a version of the TPS659037. It has a unique OTP configuration, including which rails are active, the power sequence, and the GPIO configurations. The TPS659037 will specify which OTP settings are defined for the TPS6590379: www.ti.com/.../sliu011

I believe there should me no issues using the same symbol. Please let me know if you have any additional questions or issues using the symbol.

Thanks,
Nastasha

So is it correct to treat K4, K5 and L4 as NC in my design?

Johan,

Yes, these pins can be left floating.

A schematic example can be found here: www.ti.com/.../TMDXIDK5728

Thanks,
