Product Information
MB0405A
MOSFET B6 bridge for BLDC drives
Product in development
Features
 Robust, molded module solution for BLDC motors in
engine cooling, HVAC, Automatic transmission actuators
and others.
 Normal level MOSFETs, 40V (optional 60V or 80V),
N-Channel-Type, 100% avalanche tested
Customer benefits:
 B6 bridge MOSFET module with integrated shunt and
slug-up cooling
 Quick mounting
 Improves system safety and system reliability
 50% less space compared to discrete solution
 Shunt resistor in common ground path
 On-chip temperature sensor (optional)
 Optimized internal impedances for reduced voltage
overshoot and better phase balance
 Optimized thermal connection for just one contact area
per module
 SMT package for standard PCB mounting
 Narrow mechanical tolerances for slug-up on pcb:
opposite side of pcb can be fully utilized.
 ROHS compliant, halogen-free
The compact MB0405A is designed to drive 3-phase BLDC
motors.
The modules is specifically designed for environments
where high currents have to be handled, space is limited,
