Interfaces Directly with Most Brushless Motor Drive IC's
55 Volt, 10 Amp P-Channel, 30 Amp N-Channel
DESCRIPTION:
The MSK 3018 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 3018 will interface directly with most brushless motor drive IC's without special gate driving require-
ments. The MSK 3018 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 3018 is a replacement
for the MPM3003 with higher current capability when turning on all the N-Channel FETs for braking.
