OptiMOS™ 7 motor-drives optimized are available in the following packages below to meet your design requirements:

  • SuperSO8
  • PQFN 3.3x3.3

SOA is a critical attribute of a MOSFET in a motor drive application. The SOA diagram in a datasheet defines the allowed maximum current-voltage range of a MOSFET.

In motor drive applications, a wider SOA provides higher current capability and better reliability, especially during locked rotor and short-circuit scenarios. The OptiMOS™ 7 Motor-drive optimized MOSFET family has been shown to have 3 times wider SOA than the previous generation MOSFET family in the same voltage class. 

The value of induced voltage on the gate (induced VGS) of a MOSFET is a critical factor for false-turn-on in motor drive applications. During the high-side turn-on transient, the VDS of the low side MOSFET rises from 0 V to BUS voltage. The fast-increase of VDS causes current to flow through the CGD (ICGD). The current ICGD flow through RG and VGS will consequently increase causing a false turn-on.

A MOSFET with higher threshold voltage (VGS(th)) has higher immunity to induced VGS.

The threshold voltage (VGS(th)) of OptiMOS™ 7 motor drive optimized MOSFETs is 2.8 V (typical), which is higher than OptiMOS™ 6 MOSFETs.
