Dear Valued TRINAMIC Customer,
This notification is to inform you that a change will be done to the product listed below:
• TMC236A-PA
• TMC236A-PA-T
• TMC236A-PA-X
For samples and further questions, please contact your sales partner.
Hardware changes
Due to product maintenance and to assure longevity of the TMC236 we qualified a new
wafer fab for TMC236 motor driver MOSFETs full-bridges. Hardware changes:
• Motor driver N-channel MOSFET (4pcs. in total)
• Motor driver P-channel MOSFET (4pcs. in total)
• Revision field of IC label will change from “A” to “B”. (TMC236A to TMC236B)
• New motor driver MOSFETs will improve power losses due to lower Rdson
You can find the relevant MOSFETs (red marked) in the block diagram in figure 1. Due
to the multi-chip structure of the TMC236 only motor driver MOSFET dies are affected to
the changes. Complete digital and analog part of the core die as well as lead frame and
IC structure stays unchanged.
Compatibility
The new revision of the TMC236 is fully compatible. Notes on hardware compatibility:
• No change in mechanical dimensions. Test passed.
• No change in electrical behavior of digital and analog core die. Test passed.
• MOSFET electrical characteristic (e.g. slope, break before make, Rdson) Test
passed.
• Improved behavior of motor driver stage due to lower Rdson. (Power dissipation
lower or equal to revision A)
• Assembly, production of core die and test facility stays unchanged.
• Digital and analog core die stays unchanged.
• Drop-in compatible.
