Melexis announces their new product line, ‘Protective Devices’
Melexis has announced an expansion of its portfolio with the launch of a new product line, Protective Devices. This move underscores the company’s commitment to driving innovation, safety, and extended battery autonomy in the rapidly evolving electric vehicle (EV) and energy management sector.
The new product line will be led by Billy Ye, Product Line Director for Protective Devices. He will focus on delivering highly reliable, specialised solutions that safeguard sensitive electronic components while maximising the efficiency of high-voltage systems.
The first product launched in the new line is the MLX91299, a solution designed for Silicon Carbide (SiC) power modules. These modules are fundamental to increasing the driving range and improving the efficiency of EVs.
The MLX91299 is an integrated silicon-based RC snubber circuit that provides two critical benefits:
Protection: It mitigates high-frequency oscillations, voltage transients, and parasitic effects that occur during the fast switching of SiC devices, which are major sources of electrical stress and instability.
Power Saving & Range Extension: By effectively damping these high-speed effects, the snubber can reduce critical switching losses by up to 50% (according to initial measurements). This improved efficiency means less wasted energy as heat and more power delivered from the battery to the wheels, thereby helping to save power and directly extending the driving range of electric vehicles and many other industrial applications.
