With the expansion of Microchip’s SiC portfolio, designers will be also be equipped with new tools to develop smaller, lighter and more efficient solutions for electrified transportation, renewable energy, aerospace and industrial applications.
System designers of traction power units (TPUs), auxiliary power units (APUs), solid-state transformers (SSTs), industrial motor drives and energy infrastructure solutions who require high-voltage switching technology to increase efficiency, reduce system size and weight and enhance reliability will benefit from these new devices.
At present, many silicon-based designs have reached their limits in efficiency improvements, system cost reduction and application innovation.
While high-voltage SiC provides a proven alternative to achieve these results, until now, the availability of 3.3 kV SiC power devices was limited. Microchip’s 3.3 kV MOSFETs and SBDs join a comprehensive portfolio of SiC solutions that include 700V, 1200V and 1700V die, discretes, modules and digital gate drivers.
These new SiC power devices include MOSFETs with the industry’s lowest RDS(on) of 25 mOhm and SBDs with the industry’s highest current rating of 90 amps. Both are available in die or package form. These new levels of performance will, according to Microchip, enable designers to simplify their design, create higher-power systems and use fewer paralleled components for smaller, lighter and more efficient power solutions.
“We focus on developments that provide our customers the ability to quickly innovate systems and move their end products into a competitive advantage position faster,” said Leon Gross, vice president of Microchip’s discrete product business unit.
“Our new family of 3.3 kV SiC power products allows customers to move to high-voltage SiC with ease, speed and confidence and benefit from the many advantages of this exciting technology over silicon-based designs.”
Customers can combine Microchip SiC products with the company’s other devices to create complete system solutions at a lower overall system cost.
The expanded SiC portfolio is supported by a range of SiC SPICE models compatible with Microchip’s MPLAB Mindi analogue simulator modules and driver board reference designs. The Intelligent Configuration Tool (ICT) enables designers to model efficient SiC gate driver settings for Microchip’s AgileSwitch family of configurable digital gate drivers.
