High-Voltage Auxiliary E-Fuse Reference Design
Microchip's auxiliary E-Fuse technology high-voltage solid-state relay has overcurrent protection
Microchip offers high-voltage auxiliary E-Fuse technology in hybrid electric vehicle (HEV) and electric vehicle (EV) applications. This technology demonstrator leverages the benefits of 700 V and 1200 V silicon carbide mSiC™ products to provide a complete solution. This design also implements a time current characteristic (TCC) curve that helps users migrate to non-automotive applications such as DC solid-state circuit breakers.
Features
- Configurable current limit profile
- LIN communication interface for configurability and diagnostics
- High-side or low-side drive configuration
- Short-circuit withstand time: 10 µs
- Rated current: 30 A
- Low-voltage operating range: 9 V to 16 V
- Up to 20 kHz switching frequency
- High-voltage operating range: 200 V to 900 V
- Operating temperature range: -40°C to +85°C
- Automotive hardware design that uses only AEC-qualified components
- Six variants of this high-voltage auxiliary E-Fuse design support 400 V and 800 V bus voltages and continuous current ratings of 10 A, 20 A, and 30 A
Applications
- EVs
- HEVs
- DC smart grids
- Industrial
- Charging stations
