ADI TMC424

SPI1,5 В, 3,3 ВПоверхностный монтаж

Overview

The TMC424 is a triple incremental encoder input chip, which interfaces to any SPITM compatible controller. The TMC424 can especially be used in conjunction with the TMC428 triple stepper motorcontroller to provide position verification or stabilization using some additional software. It integrates 24 bit counters for each encoder to provide a high position resolution without CPU interaction. Furtherit allows dynamic resolution adaptation to allow direct comparison of encoder counters with motors using a different micro step resolution. All encoder counters can be latched synchronously, or whenever a null channel event occurs, providing a position on strobe holding function. The TMC424 also provides a step / direction output with programmable signal shaping for the TMC428 as an optional function. A multiplexer function is also integrated for the TMC428 reference switches. Allfunctions can also be used in conjunction.
