The road to 900-V-powered electric vehicles is being paved by onsemi’s partnerships with NIO and Geely, exploiting EliteSiC technology to make it happen.
A previous current limiter works well at low supply voltages but lacks precision above 10 V. This improved version reacts quickly to protect the circuit from drops in load resistance at higher voltages.
Most common current-limiting implementations have a voltage drop that’s too high for today's systems with low-voltage supply rails. This design is a better fit.
