Conclusion

Semiconductor-based smart fuse solutions are gaining popularity over traditional melting fuses in automotive power distribution given their significantly improved fuse time-current characteristics and resettability through software. These benefits enable a reduction in overall cable harness weight because the cables are thinner and shorter.

One of the system design challenges with semiconductor-based smart fuse solutions is whether the capacitor load charging can meet the system startup time requirements. TI’s high-side switch controller devices offer various techniques to address the challenges of capacitive load driving.
