The TMC34NP-PSO is a miniature N & P channel MOSFET complementary pair, ideally suited for motor drive applications. It perfectly complements the TMC239A-LA / TMC249A-LA stepper motor drivers, in order to build a 4A stepper motor driver the size of a stamp.
The evaluation board has different stepper driver MOSFET configurations and allows SPI control via a TMC428 eval board as well as step / direction control using a TMC401.
