14 MOSFET Examples
There are a number of N- and P-channel paired MOSFETs available suitable for the TMC262, 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 gate charge below 20nC (at 5V) is best for reaching reasonable slopes.

* The maximum motor current applicable in a given design depends upon PCB size and layout,
because all of these transistors are mainly cooled through the PCB. The data given implies
adequate cooling measures in the design, especially for higher current designs. The maximum
RMS current rating takes into account package power dissipation, on resistances, and gate
charges.
