●Dear Valued TRINAMIC Customer, This notification is to inform you that a change will be done to the product listed below:
■TMC261-PA
■TMC261-PA-T
■TMC261-PA-X
●For samples and further questions, please contact your sales partner.
●Hardware changes
■Due to product maintenance and to assure longevity of the TMC261 we qualified a new wafer fab for TMC261 motor driver MOSFETs full-bridges. Hardware changes:
▲Motor driver N-channel MOSFET Upcs. in total)
▲Motor driver P-channel MOSFET Upcs. in total)
▲Revision field of IC label will change to "A". (TMC261 to TMC261A)
▲New motor driver MOSFETs will improve power losses due to lower Rdson
■Due to multi-chip structure of the TMC261 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 TMC261A 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 inital revision)
▲Assembly, production of core die and test facility stays unchanged.
▲Digital and analog core die stays unchanged.
▲Drop-in compatible.
●This improvement is classified as a minor change.
