Motor based on the BLDC(brush-less direct current)overcomes the congenital defect of brushed DC motor,in
which the mechanical commutators are replaced by electronic commutators.As such,BLDC motor offers the
benefit of easy speed adjustment of the brushed DC motor as well as the simple structure of typical AC motor.
On top,BLDC motor does not create high-voltage sparks when the direction of rotation is changed,operates
reliably,and is easy to maintain.Because electronic inverter is used to convert the direct current input into
alternating current to drive the respective stator coils,BLDC motor is effectively a three-phase PMAC
(permanent magnet synchronous AC motor)with sensor output to tell the rotor position.
JJM low and medium voltage MOSFETs are widely used in the field of motor drives, such as battery powered tools, ceiling fans, electric 2/3 wheelers, gardening tools, vacuum cleaners, and so on, with the following advantages:
Outstanding ON-resistance RDS(ON)to minimize the operating temperature and conduction loss,strong
avalanche performance EAS to sustain high surge without damage(e.g.JMTG035N04A)
Exceptional input gate charge Qg hence low switching loss and the ability to support high switching
frequency.All these allow the operating temperature to be reduced and better long-term reliability to be
VDS_Max ranges from 30V to 150V,RDS(ON)is as low as 0.55m(e.g.JMSL030SAG)and 0.57m(e.g.
JMSL040SAG),FOM is as low as 47
Assembled in highly thermally efficient power packages like PDFN3x3/5x6-8L,DFN2020-6L,
All electrical parameters exhibit negligible lot-to-lot variation and good long-term reliability
Complete product portfolio to meet the diversified requirement on performance requirement,price
expectation,and application space constraint,etc.
Depending on the breakdown voltage VBR(DSS)_Min requirement,JJM offers 30~100V Trench SGT
MOSFETs based on trench or SGT technology platform from 30V to 200V for motor driving under various
application environment.System engineers simply select the right MOSFETs based on output power and
average current requirement.
