3 Summary

The growing EV market and trends towards higher voltage, lower volume batteries necessitate a safer, more reliable, and scalable design for HV measurement. Current discrete designs fall short of a design because of the size, problems associated with exposed nodes, and more involved BOMs. Integrating the voltage divider results in a smaller design with a more precise resistor ratio and longer lifetime. Depending on whether the system requires extra protection and control, either the TPS4141-Q1 or RES60A-Q1 are fit to deliver all the advantages of an integrated design.
