CHANDLER, Ariz., May 09, 2023 (GLOBE NEWSWIRE) — High-voltage electrical subsystems throughout Battery Electric Vehicles (BEVs) and Hybrid Electric Vehicles (HEVs) require a mechanism to protect the high-voltage distribution and loads in the event of an overload condition. To provide BEV and HEV designers with a faster and more reliable high-voltage circuit protection solution, Microchip Technology (Nasdaq: MCHP)<\/strong> today announces the E-Fuse Demonstrator Board<\/strong><\/a>, enabled by silicon carbide (SiC) technology, available in six variants for 400\u2013800V battery systems and with a current rating up to 30 amps.<\/p>\n

The E-Fuse demonstrator can detect and interrupt fault currents in microseconds, 100\u2013500 times faster than traditional mechanical approaches because of its high-voltage solid-state design. The fast response time substantially reduces peak short-circuit currents from tens of kilo-amps to hundreds of amps, which can prevent a fault event from resulting in a hard failure.<\/p>\n

\u201cThe E-Fuse demonstrator provides BEV\/HEV OEM designers with a SiC-based technology solution to jumpstart their development process with a faster, more reliable method for protecting power electronics,\u201d said Clayton Pillion, vice president of Microchip\u2019s silicon carbide business unit. \u201cThe E-Fuse solid-state design also alleviates long-term reliability concerns about electromechanical devices because there is no degradation from mechanical shock, arcing or contact bounce.\u201d<\/p>\n

With the E-Fuse demonstrator\u2019s resettable feature, designers can easily package an E-Fuse in the vehicle without the burden of design-for-serviceability constraints. This reduces design complexities and enables flexible vehicle packaging to improve BEV\/HEV power system distribution.<\/p>\n

OEMs can accelerate development of SiC-based auxiliary applications with the E-Fuse demonstrator because of the built in Local Interconnect Network (LIN) communication interface. The LIN interface enables the configuration of the over-current trip characteristics without the need to modify hardware components, and it also reports diagnostic status.<\/p>\n

The E-Fuse demonstrator leverages the unrivaled ruggedness and performance of Microchip\u2019s SiC MOSFET technology and PIC\u00ae<\/sup> microcontrollers\u2019 Core Independent Peripherals (CIPs) with a LIN-based interface. The companion components are automotive-qualified and yield a lower part count and higher reliability over a discrete design.<\/p>\n

Microchip\u2019s SiC power solutions provide the industry\u2019s broadest and most flexible portfolio of MOSFETs, diodes and gate drivers in bare die, discretes, modules and customizable power modules.

\n Development Tools<\/strong>\n <\/p>\n

The E-Fuse Demonstrator Board is supported by MPLAB<\/strong>\u00ae<\/strong><\/sup> X Integrated Development Environment (IDE)<\/strong><\/a> to enable customers to quickly develop or debug software. The LIN Serial Analyzer<\/strong><\/a> development tool allows customers to easily send and receive serial messages from a PC to the E-Fuse Demonstrator Board.<\/p>\n

\n Pricing and Availability<\/strong>\n <\/p>\n

The E-Fuse Demonstrator Board is available in limited sampling upon request. For additional information, contact a Microchip sales representative<\/strong><\/a>.<\/p>\n
