The TMC2209 is the ultimate stepper driver for desktop solutions, allowing stall detection and extremely silent operation at the same time. Pin-compatible with a number of legacy drivers, it supports higher current while reducing cooling requirements.
The TMC2209 pin compatibility makes it the perfect candidate for existing design upgrades and bringing improved applications to the market. With the new feature set, the chip is ideal for POS devices, 3D printers and conventional printers, office and home automation, textile, security cameras and ATM machines, as well as battery operated equipment.
