8.2 MOSFET examples
There is a huge number of MOSFETs on the market, which can be used in combination with the
TMC603. The user choice will depend on the electrical data (voltage, current, RDSon) and on the
package and configuration (single / dual). The following table gives a few examples of SMD MOSFETs
for different motor currents. The MOSFETs explicitly are modern types with a low total gate charge.
With dual configurations, only three MOSFET packages are required to control a BLDC motor, but the
current which can be reached is significantly lower due to thermal restrictions of the packages.
For the actual application, we suggest to calculate static and dynamic power dissipation for a given
MOSFET, as described in the previous chapter. Especially for sine commutation and chopper
frequencies above 20kHz, transistors with a gate charge below 100nC should be preferred.

(*) Remark: The maximum motor current applicable in a given design depends upon PCB size and
layout, since all of these transistors are mainly cooled via the PCB. The data given implies adequate
cooling measures taken by the user, especially for higher current designs.
