15 MOSFET Examples
There are a many of N- and P-channel paired MOSFETs available suitable for the TMC2590, as well as
single N- and P-devices. The important considerations are the electrical data (voltage, current, RDSon),
package, and configuration (single vs. dual). The following table shows a few examples of SMD
MOSFET pairs for different motor voltages and currents. These MOSFETs are recent types with a low
total gate charge. For the actual application, you should calculate static and dynamic power
dissipation for a given MOSFET pair.
A total gate charge Q
G
below 40nC (at 5V) is best for reaching reasonable slopes.
The performance (Q
G
and R
DSon
) of the low-side MOSFET contributes to 70% to the overall efficiency.

* For duty cycle limited operation, 1.5 times or more current is possible. The maximum motor current applicable
in a design depends upon PCB size and layout, because all of these transistors are mainly cooled through the
PCB. The data given implies a certain board size and layout, especially for higher current designs. The maximum
RMS current rating is a hint and is based on measurements on test boards with given size at reasonable heat
up. Estimations for not tested types are based on a comparable type (estimated board sizes marked e).
