25milli ohms on-resistance complementary
MOSFET pair for DC motor control apps
Diodes Incorporated has announced the DMC4040SSD complementary
dual MOSFET for use in low voltage, single- and three-phase
brushless DC (BLDC) motor control applications. The DMC4040SSD
features matched N-channel and P-channel Rds (on) performance
of 25milli ohms at a Vgs of 10V to ensure DC losses in motor
loads are balanced and minimized.
The enhancement mode MOSFET pair is rated with a Vds of
40V, making them suitable for 24V DC motor systems controlling
cooling and extractor fans, pumps, compressors and printer
heads.
The DMC4040SSD has a continuous current rating of 6A and
a pulsed current rating of 29A, enabling motor torque currents
of up to five times the continuous current to be supported
during motor start up or stalled motor conditions.
Packaged in the industry-standard SO-8 package, the DMC4040SSD
device will also bring PCB space-saving advantages over
single MOSFET package alternatives.
To create a complete high-efficiency BLDC motor control
solution, the DMC4040SSD MOSFET package can also be deployed
in conjunction with Diodes' own range of ZXBM102x single-phase
and ZXBM200x two-phase pre-driver 2 motor controllers and
companion Hall sensors.
