TPS65218: 101, D0, differences

Lenio Cacula

Part Number: TPS65218


Team,

I would like to confirm what the differences are between the following three variations of TPS65218:

TPS65218B1

TPS65218B101

TPS65218D0

Are there differences other than the hysteresis of the undervoltage lockout between those parts? (0, 200, 400mV)

Thank you!

    Hi Lenio,

    I've assigned this post to the appropriate applications engineer, he will respond to your question.

    Regards,

    The TPS65218B1 and TPS65218B101 both share the same datasheet and generic part number of TPS65218. As a result, the differences between these to devices can only be a result of default OTP settings for the Register Map. Specifically, the UVLOHYS bit (bit 6 of Reg. 0x14).

    However, the TPS65218D0 is a unique GPN that is targeted towards the AM438x Sitara processor (as opposed to the TPS65218 which is for the AM437x processor and additionally supports AM335x via a linux kernel driver).

    Since this -D0 version is using an alphanumeric code as the suffix, it is a die revision and it cannot be assumed that the Register Map default settings are the only difference. Both analog and fundamental digital changes can be made when a die revision occurs.

    Lenio,

    UPDATE: For new designs, the TPS65218D0 is recommended over the -B1 release. Although the -B1 version is not officially listed as NRND, this process has been started.

    The Revision History for the -B1 datasheet (Lit # SLDS206, Rev. C) explains some of the spec changes made for -B1 silicon that were made permanent or corrected in the -D0 silicon update.
