IX/fSf^ THREE PHASE BRIDGE OHHI MOSFET POWER MODULE OUU I M.S.KENNEDY CORP. • P and N Channel MOSFETs for Ease of Drive • Isolated Package for Direct Heat Sinking, Excellent Thermal Conductivity • Avalanche Rated Devices • Interfaces Directly with Most Brushless Motor Drive IC's • 100 Volt, 5 Amp Full Three Phase Bridge at 25°C The MSK 3001 is a three phase bridge power circuit packaged in a space efficient isolated ceramic tab power SIP package. Consisting of P-Channel MOSFETs for the top transistors and N-Channel MOSFETs for the bottom transis- tors, the MSK 3001 will interface directly with most brushless motor drive IC's without special gate driving require- ments. The MSK 3001 uses M.S.Kennedy's proven power hybrid technology to bring a cost effective high perfor- mance circuit for use in today's sophisticated servo motor and disk drive systems. The MSK 3001 is a replacement for the IRFT001 with only minor differences in mechanical and electrical specifications.

APPLICATION NOTES N-CHANNEL GATES (Q1,Q3,Q5) For driving the N-Channel gates, it is important to keep in mind that it is essentially like driving a capacitance to a sufficient voltage to get the channel fully on. Driving the gates to +15 volts with respect to their sources assures that the transistors are on. This will keep the dissipation down to a minimum level [RDS(ON) specified in the data sheet]. How quickly the gate gets turned ON and OFF will determine the dissipation of the transistor while it is transitioning from OFF to ON, and vice-versa. Turning the gate ON and OFF too slow will cause...
