Features
The TMC249 / TMC249A (1) is a dual full bridge driver IC for bipolar stepper motor control applications.
The TMC249 is realized in a HV
CMOS technology and directly drives eight external LowRDS-ON high efficiency
MOSFETs.
It supports more than 6000mA coil current.
The low power dissipation makes the TMC249 an optimum choice for drives, where a high reliability is desired.
With additional drivers, motor current and
voltage can be in...
